I threw a very small handful of Ammonium Sulfate in the pool yesterday. For some reason there is no algae growing in the pool. I think it's because of the calcium bentonite clay. I remember last year when I threw in fertilizer. The pool greened up within hours! I've read that the clay prevents algae but I never would have believed how well.

Does anybody have any good ideas for stocking my pool with some plants? I am at least a two hour drive from the nearest lake. I wouldn't mind getting some seaweed from there and seeing if I can get it to grow.

Is there anything I can start by seed maybe?
