I buy this as a staple in my medicine chest. Works great on many types of fish.
I try to order supplies here whenever I can, because Corey does so many helpful and interesting videos offered free on YouTube. I've had great experiences with every order and product. Support quality small businesses like this one!
I bought this to treat hydra in my shrimp tank after several reviews from this site. It arrived very quickly and I was excited to be able to treat quickly. After a week there's more hydra than ever and I've lost about half of my breeding stock.
Despite several other reviews, I don't consider this shrimp safe and it doesn't treat hydra.
The good news is it eradicated the few detritus and rhabdocoela worms on the first day.
