Re: Planaria and Hydra Elimination in Shrimp Tanks I want to say, I used this on the two tanks that were affected. I am unsure, but I think it did kill off my nerite snails I had in the tanks at the time. So I might warn that it is possible to wipe out your nerites. Other than that, not a hydra left. I think I did od by mistake the one tank because the hydra all fell off within an hour of treatment.
Worked well. Just remove all "pet" snails |
