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 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.

If I have not listed very many as available and you want to order more OR if I haven’t listed the size you want, that just means you should contact me (I can do large orders) I just need to check the shipping for the quantity you want and I’ll send you a paypal invoice for the order.  Please include the shipping address, size, quantity, and fittings for the airstones you want, when you contact me and I’ll find out the shipping cost and get you the invoice.  If you don’t hear back from me ASAP check your spam folder.

Simply put these are the highest quality air diffusers on the market today !!!!

Made of 100% glass bonded silica each item is hand tooled in BubbleMac’s Central Florida shop.

BubbleMac diffusers are time tested and proven, considered the “industry standard” for 35 years.

The round grain pore structure, low resistance and uniform porosity make BubbleMac diffusers an excellent choice for aquaculture, Aquaponic, Hydroponic, wastewater and lake aeration applications.

Durable, low maintenance and manufacturer guaranteed for 2 years. BubbleMac brand air diffusers produce a uniform bubble and with an air resistance of less then 0.25 psi are compatible with most low pressure blowers. In most soft water applications, you won’t need to clean this diffuser for more than a year.

The BubbleMac air diffuser is not an imitation or copy.

Proudly Made in the USA

Body : 2000°F Glass-Bonded

Fitting : Linear Polyethylene

Maximum Pore Size : 1-3 mm

Nominal Particle Retention : 50 microns

Unlimited service life at pH below 8.0

BEWARE OF IMITATIONS……. BubbleMac diffusers are the original 2000° F glass-bonded silica diffusers introduced in 1978 by Bob Heideman, founder of Aquatic Eco-Systems. The “other guys” may try to copy our sizes, descriptions and even our photos, but it takes more than flattering imitation to compete with “the best.” Look for the name and the two-year warranty. Made in the USA.

Sweetwater Air Diffuser – “REPLACEMENTS” — by Bubblemac Aeration Products
Please take a moment to review a recent letter from the President of Bubblemac Industries, Inc.

As some of you folks are aware, Bubblemac Industries, Inc. has been the “sole” {and silent} manufacturer of the high-quality “Sweetwater” glass-bonded silica air diffuser line, since January, 2000. Our Central Florida machine shop has also produced the well-known Bio-Weave air diffuser hoses, since the design development in 1995. Each of these trademarked product lines have been distributed exclusively by our Apopka, Florida neighbor; Aquatic Eco-Systems {now Pentair Aquatic Eco-Systems}, for the same number of years.

As is sometimes the case when the “giants” get involved in industry, more emphasis is put on profits and the bottom line. The drive for these huge organizations is to increase profits by using more imported parts and pieces in place of quality American Made parts. While many of these massive corporations, with interests in virtually every country on the globe, do reach their profit goals through this practice; too many times it is the consumer who ultimately pays the price by dealing with defective or inadequate systems that fail to meet the expectations for the application.

Effective June 1, 2015; after 15+ years; Bubblemac Industries, Inc. is no longer producing the “Sweetwater” air diffuser line for Pentair AES.

Our longtime, largest distributor has opted for an alternative product, rumored to be a molded style air stone with a “plug” on one end. As we understand it from several longtime Pentair AES customers who have contacted us; these “new” products are being sold to unknowing buyers with no prior indication there is a difference.

The Bubblemac Aeration Products design of the 100% Glass-Bonded Silica Air Diffuser “IS” and “ALWAYS HAS BEEN” the original design introduced by Bob Heideman, founder of AES, in the late 70’s. Our high-quality air diffusers are machined from a solid block of silica, with hand crafting in each and every air stone. Well known and recognized worldwide for many years as the standard of the industry for aeration.

Being of strong faith and moral conviction, the hard working and experienced employees at Bubblemac firmly believe that, “with every door that is closed; another will be opened.”

We will continue to manufacture the highest quality silica air diffusers on the market. We will continue to provide these products “on-time” to our customers and at a fair price. We assure that our service and order follow-up will far exceed that of our; now competitor, Pentair AES, in Apopka. Please visit our website regularly to review new products and specials. And of course, please call if we can assist with your aeration needs.

Thanks for your business.

They range in size from .5″ x .5″ x 1.5″ all the way up to 1.5″ x 1.5″ x 12″ and come with Linear Polyethylene fittings in several different sizes (1/4″ Barb, 3/8″ Barb and 1/2″ MNPT) and can ship internationally.
