I've got snails multiplying like crazy in one of my units at petco (Marineland MARS system. I know loaches and some other fishes will eat snails, but since they're in the sump and filters and everywhere else, a preditor is not a vyable solution. I hate using chemicals, but in this case I don't see any other option. Does anyone know any product that will wipe out the snails, regardless of whether the treatment is intended for that purpose, or whether their demise is a side effect? Thanks!
