This is a Kelp product that has nitrogen in it so be careful not to overload the bio-filter if you use any in a system with fish. This would be a nice supplement for worms to provide trace elements and added potassium, it is also a great fertilizer in general and many people also supplement animal feed with kelp meal.

Hello,
Please let me know if you ship the kelp meal to Brazil.
Thank you!

I’m Sorry but for the supplements and pest controls, I do not know the regulations for shipping those internationally (it is probably different for every country too) so I do not ship those outside the USA.
