I have an outbreak of cyanobacteria in one of my tanks. I am now to the point where I would like to try Erytomycin along with my water changes. My question is, do I need to remove may SAE (It took a two hour drive to get them) to another tank? Will the Erytomycin have an adverse effect on my shrimp or ramshorn snails? Any comments would be appreciated. Doug Martin
