I mean live snails- the nuisance snails that hitchhike on plants. I think I'm going to get a 50 gallon tank for my planted sorority/community tank when I move into my new house in November. (yay!

)
My 5 gallon was cycled in less than 3 weeks with my betta in it, but I know with a bigger tank it will take longer. BUT I was wondering if it would speed up the process if I used snails as my ammonia source. Do all snails produce a lot of ammonia or just certain kinds? Snails are hardy so they won't die easily from ammonia spikes, right? Would I have to have plants and sand in it while I cycled or could I cycle it with just the snails in it? If I use sand I think it would be more difficult to find all the snails to remove them again (and hopefully give them away or sell them to someone on here). But I know the sand and plants also holds a lot of the BB in a tank so will it mess up my cycle when I add in the sand and plants?
Or is this a really dumb idea because even if I think I've gotten all the snails out I probably didn't and will continue to get overrun with snails?
