guys

today me and flashout had visit 3 home gardening shop, none of them carry clay. one of the owner told us to use red soil in stead of clay.

the purpose of finding is to use it in our planted tank. my plan is to make it at the bottom layer. have did some checking on the net, and seems like clay good for plant with roots


is it a non commercial item? that it can only be acquire by getting it from nature?

would prefer if can buy it in stead. no idea where to find.

thanks!
