We sell Red Clay by the pound. You can add one pound of red clay to any planted tank substrate. One pound is enough for a 20 gallon aquarium. Ever tank is different, but if you want a general rule of green thumb, one pound per 20 gallons of water is a good amount. The clay is red and contains high amounts of Iron which is what your plants love. Plants absorb 40 to 400 times more iron through their roots. Pair this with our Alternathera Reineckii "Variegated" to see the full effect of this Clay!

By adding clay to your planted tank. You are feeding your plants where they are eating. You can see in my many videos how the roots grow toward the clay. Get your plants some clay, even if you aren't ready to convert to dirt, this way you can start to see the power that feeding your plants at their roots provides. Don't believe yet that plants LOVE CLAY? Check out how the roots of my plants grow into it in this video...

Red clay

I made marble size chunks and buried in substrate but not deep enuff on a couple so it clouded tank big time. Rookie mistake. Just make sure you push it as deep as possible.

It's clay

It's clay, i put it in the the substrate and its doing what its supposed to do. i think.


I put one ball of clay in my 37 gallon and it made the water dirty.


I use laterite in my planted aquariums and thought I would try the clay. I'm very pleased with this product. I use it as a small ball for root tabs and it great for my plants! Very satisfying! It's very hard these days to find iron clay. Dustin did good by coming out with this product!
