There's not much info out there on this product. So I'll give my review so that it might help you.
TL;DR shrimp safe, seems to work on planaria, doesn't work on hydra.
The good thing is that from my experience it is shrimp safe. Also my ramshorn snails were fine.
My friend bought this product for planaria and it seemed to work fine. Not sure how thorough of an experiment he did but he reports that he rarely sees planaria now. He used to see a few everyday.
I took some of his gei lee product for hydra in my tank. I followed instructions and even overdosed a little as the initial treatment did not affect hydra whatsoever. I dosed nearly everyday but nothing. I even took multiple hydra out of the tank and put a bunch of gei lee on top of them. Since then they have multiplied and seem unaffected.
It successfully killed all the Planaria in less than 2 days, my fish and most pond snails are fine. Thanks.
Works as intended
