Shipping

Please check the shipping address listed in your paypal transaction as you check out! If that address is wrong contact me ASAP since I pack and ship orders quickly and I do it based on the address paypal gives me. I prefer you have a confirmed paypal address since unconfirmed addresses mean I need to confirm the shipping address with you (this takes time and can delay shipping.) If you get an e-mail from me with a subject like Re: Payment received from your e-mail@your e-mail.com it is me trying to confirm something about your order before I can ship, please open it and respond if you want your order shipped asap.

I do not earn money on the shipping. The paypal calculator is not very flexible so if it over charges you for shipping, I will refund the difference. There is a place on paypal where you can add instructions about shipping (for instance if the shipping address is a business address according to UPS/Fed Ex it might allow me to save you money on shipping for certain products if I know about it, otherwise I have to assume residential shipping. If you add your phone number there I can use your phone number if I ship via Fed Ex for certain products and they can call you if there is an issue with delivery.)

If Paypal doesn't charge you for shipping, it is probably because you are in another country or someplace I don't normally ship to, I will be contacting you about it since I will need to find out the shipping costs to your location and send you an invoice for the shipping or refund your order if I can not ship to you or if you don't want to pay the shipping. I normally Sell in the USA but have occasionally shipped packages internationally.

Plants and Fish I only sell in Florida at this time and I am not set up to ship fish yet.

Return and Refund Policy

I try very hard to quickly answer questions about products before the sale. If you are uncertain about a product please ask, I want to make sure that what you buy is what you need and what will actually work for you.

If you buy a product and change your mind about it later and want to return it, I will have to charge a re-stocking fee and I can only accept returns on unused items. I can only make refunds for 60 days after the purchase through paypal. I do not refund the shipping or pay return shipping unless the reason for the return is on my end.

Please contact me for instructions before returning anything. If I'm not expecting something to come back, I won't know what to do with it if it actually makes it to me. Some packages are shipped direct from the manufacturer and simply mailing something back to them won't get you a refund.

If there is a problem with a product, please contact me so we can work something out. Some items are covered by warranty.

Aeration Equipment

I can provide air pumps, tubing, stones etc.
Give me a bit to get them up on the site (and I can probably get other sizes of stuff if necessary but I’ll start off with the things I have already used myself.)

The vague rules of thumb I’ve been operating under for the last several years are, you want about a cubic foot of air per minute for each 400 gallons of fish tank. It takes aprox 1 psi to push air through the air stone and 1 psi to push air down under each 28 inches of water depth. So for a 300 gallon tank that is less than 28 inches deep, look for an air pump that can deliver .75 cfm at 2 psi and you should be good. Make sure you get enough air stones rated for the amount of air flow that will be available at the water depth you will have since restricting the flow out of an air pump by not letting it go somewhere will heat up the pump and shorten it’s lifespan. See the air stones have a rated amount of air that can pass through them in a given amount of time.

Now if there is plenty of water flow a system might not need supplemental aeration from an air pump but I always find, especially in our warm summers, that the fish eat better when there is extra aeration and the extra water movement provided by the air bubbles tends to help move the solid waste out of the fish tank and off into the grow beds. Too much air would be if you are boiling the poor fish out of the tank with the bubbles or when there is no water in the tank. I also find that in the bigger systems, it might be too much to run the water pumps on the battery backup but running an air pump on battery backup is within reason.

So, I’ll be working on adding items to this product category and in the mean time, contact me if you need anything related to Aquaponics Aeration and I can work up a price for what you need and let you know.

    I need an aerator pump and stones for my 300 gallon aquaponics (catfish) tank. Please be good enough to advise if you can supply: and, of course, how much it will cost.

    Thanks

    • TCLynx

      How deep is the tank? That will affect the pressure needed to supply at least 0.75 CFM of air to the tank.
      I can supply equipment though I don’t have most of it listed on my site yet. If you can tell me a little more I can probably put together a package for you.

      • Ron

        I would like some advise as well on the best aerator for my 275 gal Tote system. Also where is the best place to get one?

        • TCLynx

          To figure out the BEST aeration system for your system I would need to know more about it, Like, is it just flood and drain media beds with a 275 gallon tote fish tank? Are there any raft beds or filters that require extra aeration? How many fish/how big are you going to be stocking in that fish tank? Will your water pump be running constantly or is it going to be on a timer? Will there be extra flow from the water pump helping aerate the water also? What sort of temperatures will the water be experiencing? What kind of fish?

          Without knowing the answers to the above questions, about all I can say is
          This air pump would probably be sufficient for that size fish tank if reasonably stocked

          Great value for a low cost.
          These large outdoor air pumps have aluminum covers and internal noise-absorbers. Although the pump housings are waterproof and designed for outdoor use, the pump is not UL-listed.

          Pumps include 6′ power cord, 3/8″ hose barb, flexible outlet adapter, and outlet adapter to aquarium tubing (3/16″). Six-month warranty, 115V/60 Hz.
          Air pump
          Outdoor Air Pump with 6-outlet adapter, 25 W, 3/8″ Barb $75.95

          Air stones and airline tubing would also be required but the total cost could probably be kept under $100 not including shipping or sales tax
          I can sell the equipment, use my contact form if you would like me to put together an appropriate package for your system.

  • Hal Luebbert

    Ooops – sorry (I’m tired, I guess). I’ve “clicked” on “products” here, see the pump I seem to need.
    I’ll order. Thanks, again.

  • TCLynx

    There are two air pumps I get most often. One of them would probably be just big big enough for a 300 gallon fish tank in an aquaponics system (that is less than 28 inches of water depth) and that air pump would run $69.99

    The bigger pump is $102.99 and I use it for up to 800 gallons of fish tank.

  • Hal Luebbert

    Double oops – the pump wasn’t an aerator. I still need an aerator pump and stones. Thanks (how did my picture pop up here?)

    • TCLynx

      So how deep is the tank Hal?

      And I’m not sure how your pic poped up here? Are you signed into something that attaches your profile picture from somewhere else or something?

  • Samuel Caspers

    I am starting a small tilapia breeding business with a friend. We have 2 800gallon cylinder tanks. What air pump and stones do we need. Each tank will have 135 Blue Tilapia.

  • TCLynx

    To know for sure what aeration equipment you need, it would help to know how deep the tanks are.

  • Ray

    i am looking for a bubble pump with battery backup for 2000l tank 700mm deep,normal pump aeration is fine but I need something in case of mains power failure

    • TCLynx

      I don’t have a complete battery backup air pump system to sell. You would need to buy your own battery, inverter, and charger for the battery.

      The air pumps I have that I would recommend use only 50 watts.

      I used mine with a fail over relay so I was only running on battery power when the main power failed but would run on mains power when it was available.

      Use the contact form to send me an e-mail with your address and I can look up prices and shipping for the air pumps and stones for you.

  • Ali

    Seeking a clarification on your rule of thumb- 1cfm per 400 gallons of fish tank. What about if you are setting up a deep water raft system. So, say you have 400 gallons of fish tank and 1600 gallons in the DWC raft. How much aeration is required for the entire system? Is the thumb rule still applicable only on the water in the fish tank, or is some amount of aeration required for delivery in the raft as well?

    Any and all advice welcome!

    • TCLynx

      No the 1 cfm per 400 gallons only applies to fish tanks.

      For Raft beds, you then need 1/2 cfm every 4′ in a 4′ wide bed, so in a 4′ x 24′ bed I go in 2 feet, place a 6″ air stone that is rated to take 1/2 cfm and then thereafter place an air stone every 4 feet, for a total of 6 air stones giving the bed a total of 3 cfm.

      Now shallow water doesn’t require as much pressure to push the air down so I’ve found it to be more cost effective (air pump and electricity wise) to have a separate blower that feeds my raft beds and other shallow water applications and use a separate small air pump of appropriate size for each of my fish tanks. Since to get a blower that can push air down 48″ plus the 10″ of pressure to move the air through the air stone would require a blower that can handle a huge amount of pressure while providing quite a lot of air which would cost me big time in electricity.

      You have to size the air pump or blower to provide the total amount of air volume needed AT the highest pressure required for the system.

      I can get an air pump that uses about 50 watts and supplies enough air for an 800 gallon tank that is up to 46 inches deep. Such an air pump doesn’t provide a huge amount of volume though. Blowers can provide lots of volume but usually not very much pressure. To get a blower that can even supply any air to a tank that deep is probably going to use over 600 watts.

      So for my Current set up with 2 large fish tanks with their own air pumps and a blower providing air for the raft beds and shallow tanks, I am using a total of about 475 watts for aeration. If I were to try to do all that using only a single blower, I would have to use more than double the wattage.

  • Saira

    Hi,

    Im interested in those pumps (102.99). Whats the size, outage, power outage. Do i order them through or a different supplier?
    Thank you in advance!

  • TCLynx

    The air pumps have gone up in price a bit since the beginning of 2012.

    The larger air pump is now $106.95
    Outdoor Air Pump with 10-outlet adapter, 50 W, 3/8″ Barb
    And it will provide 2.1 CFM at 1.5 psi.
    Let me know if you want to know the output at a different pressure. I have the pump curve here but no easy way to post it in a comment.

  • Lily Meadows

    Hi
    I am having a hard time sizing an air pump and stones for my aquaponics system. Its 500 gallons, with roughly 100 tilapia. its 2′ deep… also, i am on a tight budget, but what is a good aerator that you would recommend for my tank?
    thanks so much!

    • TCLynx

      So the rules of thumb I learned.
      1 psi = 28″ of water depth.
      Most air stones are equivalent to another 10″ of water depth.
      And you want 1 CFM (cubic foot per minute of air) per 400 gallons of water.

      So for a 500 gallon tank, I would say you need an air pump that can provide 1.25 CFM at about 1.5 PSI or 34″ of water depth.
      Most reputable air pumps should have curves or charts that tell how much air they can provide at different psi or water depths.

      Now choosing the right air pump will also depend on if your system has raft beds or media beds and if the aerator will be kept in a protected room or if you need an outdoor air pump.

      I carry an air pump that is rated for outdoor use and could supply the aeration for your tank if that is all you need. At the moment it runs about $106 and the Air stones I would probably recommend run about $16.95 each and you would need two of them. There would also be some air tubing and fittings you would need but it is hard for me to make a specific recommendation without knowing where the air pump would be installed in relation to the fish tank or if there is anything else that would require aeration.

  • chris

    The green pump pictured above says its water proof but not UL listed. Would you still suggest some type of housing? I purchased one from you about a year ago and am just now getting everything setup.

    • TCLynx

      Ok I wouldn’t say “water proof” as in make very sure not to submerge it into your tank. But the housing on it is weather resistant so you don’t Have to build a housing for it unless you want to. UL listed stands for Underwriters Laboratories listing which costs a fair bit for companies to have UL labs do all their testing so not all products out there are UL listed.

    I am building an aquaponics system using and IBC tote (275 gallon size) for the fish tank. Grow beds will be flood and drain and I will have a sump tank. Water will be pumped continuously from the sump to the fish tank. I see it takes more power to push air to the bottom of one of those IBC tanks, about 40″ deep. My sump tank will be much shallower, about 24″. Can I pump air into the sump only and keep the fish happy? I will raise tilapia and want to maintain maximum density of fish. What products would you recommend? My project is in the Philippines so water temps will always be pretty high. Also, the system will be powered 100% by an off grid solar array. Voltage over there is 220 VAC, 50-60 Hz so I am shopping for components that will accept their standard power.

    • TCLynx

      Are you building this system using more than just a single IBC?

      Even if the IBC is 40″ tall, your water depth in the tank is not going to be 40″ and you are not likely to have much more than 200-250 (depending on how the cage is arranged and where you put the plumbing fitting) gallons of water in the tank even if you are not cutting the top off to make a grow bed.

      While it is cheaper do pump air down into shower water, if you are planning to stock this IBC system to it’s max fish density in a hot climate, you really need to put some form of supplemental aeration in the fish tank since even a brief failure of the water pump would then mean your fish run out of oxygen in less than an hour.

      Supplemental aeration does not have to be in the form of pumping air down into a tank, it could also be a separate water pump that simply circulates water and sprays it to aerate the water all inside the fish tank. I highly recommend some form of redundancy on the aeration for the fish tank in a Hot climate.

      If you do not have sufficient dissolved oxygen constantly being introduced into the fish tank, the tilapia won’t eat or grow nearly as well as you have likely been brought to believe. Tilapia are only amazing growers IF you can supply them with really good conditions.

      Also, you don’t mention how much flood and drain media beds your system will have. Make sure you have ample filtration to support the amount of fish you put in the tank. Just because a 250 gallon tank might be able to support x amount of fish if there is ample filtration/circulation and aeration, that doesn’t mean you get to put in x amount of fish and have them survive if there isn’t enough of the filtration/circulation and aeration.

      As to particular aeration equipment for 220 VAC I can’t make any particular recommendations on that since I use 120 VAC. However, if this is all being driven from a Solar off grid system, then you are likely talking about 12, 24, or 48 VDC power and by inverting back up to high voltage to run your air pump you will be experiencing losses by running the inverter so careful attention should be paid to the type of power system the 100% off grid install will be using before you go buying pumps for the system and don’t skimp on the battery bank or charge controllers.

    Hello,
    I am building a system with an 1100 gallon fish tank. I need to figure out what air pumps I can use for something this size. I will also have 2-1500 gallon floating raft troughs. Iwill need air for them too.

    • TCLynx

      To figure out Aeration requirements, we need to know more than just the number of gallons.
      Depth of water is important to air pump or blower calculations
      As is
      Size/shape of the Raft beds.
      For Fish tanks you need an air pump that is strong enough to pump the air down to the depth of the water in the tank while still delivering enough aeration to support the number of gallons and the fish mass in the tank. It takes 1 psi to pump air down 28″ of water depth and you can count most medium pore air stones as requiring about 10″ worth of water depth. So if your fish tank water is 46″ deep (you add 10″ for air stones) that gives a total of 56″ which would require 2 psi and for a 1100 gallon tank with an average fish load and water spraying in constantly you would probably want to supply at least 3 cubic feet per minute. So you need to look for an air pump or perhaps pair of air pumps that can give you enough air at 2 psi.
      For Raft troughs, they are generally shallower so often a blower of some sort will be better suited to providing ample volume of air at the lower pressure required. Generally you want to supply 1/2 a cubic foot of air to every 4′ by 4′ section of raft bed. So if your water depth is only 10″ and the air stones use 10″ worth of pressure, you need a blower that can supply you 1/2 a cubic foot of air per minute at 20″ or about .72 psi for every 4′ by 4′ section of bed. In my 4′ wide raft beds, I place a 6″ medium pore air stone every 4′. I don’t like wider beds because it is harder to get good aeration throughout them.

      So to answer your question for you, I would need to know the depth and planned MAX Fish load of the fish tank and I would need to know the depth and shape of the Raft beds.
      I can guess that I would probably recommend a separate air pump to provide the fish tank aeration and then a small blower to deal with the raft beds just to get the most air for the least amount of ongoing electrical usage.

  • Paul

    I’m going to raise minnows. I have a 300 gallon food grade tank, it measures 3’8″ tall and 3’7″ on all four sides. I would appreciate if you could tell me, what I need to aerate the tank or what else I need to keep the minnows alive and happy. Approx. measurements

    • TCLynx

      Hard to know for sure without knowing the exact kind of minnows and how many you intend to keep in the tank.
      You will need filtration as well as aeration and the amount depends on how much fish mass you intend to keep.

  • Bobby

    Hello and thank you for very educating post. Im planing to build aquaponics system and I have been trying for a couple of days to figure out what kind and how strong aeration system i need. I read a lot of information on the web but this post and comments are very informative. I plan to have 5000 gallon fish pond about 4 feet deep and 4,000 square feet of DWC floating rafts about 1 feet deep in 3 small greenhouses. Please correct me if im wrong, I figure out from this post that most efficient way to reduce the electricity bill would be to have separate blowers for fish and plants, for fish about 100w blower at 2psi with 2 air stones, and for the plants maybe 400w blower with air stones every 4 feet, total of 330 feet of air tubing. Im from Europe and we have temperate climate here and fish of choice would be bass, catfish or some other local freshwater fish. Any help would be appreciated. Thamk you

    run time will be 24 hours per day / 7 days a week these provide water circulation from 1 600 gallon fish tank and throughout 2
    plant beds each one 50 ft long x 3 ft wide x 16 inch deep. would prefer 48vdc devices but am flexible. if more details are needed, call Greg or Justin at xxx-xxx-xxxx. thanks in advance for your time.

    • TCLynx

      Unfortunately I don’t know of any DC powered equipment that is in any way comparable to any of those pieces of equipment.
