Well, I don't know about that, given the size of the tank. Maybe just plan on doing another one in a few days instead of waiting till the next time you'd regularly do it. The aiptaisia will melt, which means you can't exactly collect it out like other dead inhabitants, but I don't know that it will cause that much of an impact on your levels. My guess is that with it "melting", something will end up in the water to affect things, but not a whole lot like a dead snail.
