Every month I clean out my Rena xP3 filter, but over the past couple now I've noticed something a little unsightly - giant hordes of black snails that range from microscopic to almost the size of an eraser head. I know that they can be a huge risk to the life of the filter - if they grow their hard shells are supposed to be terrible if they get anywhere near the impeller.
I'm 100% certain the snails are coming from the anacharis we feed our turtle. We keep our anacharis in a water pot. After about a week or so we'll notice one or two small black snails of the same kind appear in the pot.
Two questions:
1 - is there a proper way to wash anacharis to keep it relatively free from snails? I've tried rinsing it down with tap water beforehand, but some of these snails are so small I have no idea how to keep them all away.
2 - is there a proper way to clean out the filter to help prevent this from happening again?
Thanks!
