I'm switching substrates in one of my tanks so what I'm planning on doing is taking the fish out and putting them somewhere temporary, taking a few adult Malaysian Trumpet Snails out, and then treating the entire tank with API AlgaeFix to get rid of beard algae.
Here's the tricky part: I have who knows how many baby MTS snails in the substrate and I'm worried that when I dispose of the old substrate, the snails can get into the local environment. I've heard snails are sensitive to chemicals so cruel as it sounds, I'm hoping the AlgaeFix kills the babies so I don't have to worry (main reason why I haven't used the AlgaeFix so far). If not, is there anything else I can put in the tank that will kill them? Short of panning for baby snails ala gold miner and then smashing the ones I find, I don't know how else to ensure the babies don't get into the local ecology.
I really hope this is the last time I have to switch substrates. >.<
