Dosing tank w/erythromycin - Should I save the snails?

I'm using Maracyn to knock out (hopefully) the cyanobacteria running rampant in my tank. It also has a significant population of Malaysian trumpet snails, and I read online that it kills them as well... Should I take it as a blessing? They're not my favorite things but I don't have terribly strong feelings about the snails except that there are a few too many at the moment. I haven't seen them do damage to the plants and I know that they help clean up uneaten food on the bottom of the tank.

Soo... should I save a lucky few and let them repopulate the tank? And won't dead snails significantly add to the decomposing material in my aquarium after I treat?

Lol yea, I've noticed. There's one larger (non mts) snail that I'm going to save because I like him.

But my question was more whether i should bother to save any... I wouldn't be crying if my tank didn't have MTS.

I'm basing the question on http://www.aquatic-eden.com/2006/10/maracyn-can-kill-malaysian-trumpet.html and similar from a google search... Just anecdotal evidence as far as I can tell. I don't know why antibiotics would affect MTS. Maybe they rely on some species of bacteria for their survival.

I decided to go ahead and half-dose the tank for now, and let the snails fall where they may. As bazil said, if I wanted to replace them, and I can't imagine why I would, I could just grab a couple from a lfs. Interestingly enough some of the snails are doing this weird backwards/sideways slide down the glass and then shutting the hatch. Others seem unaffected.

I plan to do large water changes after the algae starts to die off, so I'll make an effort to pull out as many of the snails as I can find... Even if they decay under the driftwood or something I can keep an eye on the levels and make sure a mini-cycle doesn't affect the fish... Gotta get a new test kit now.

Thanks for the feedback... I'll give an update on the snails when I know how it all turns out
