Snails in sump... How the heck did they get there?

[mrramsey]

This morning I discovered about a half dozen small pond snails in my sump... after the filtration in the equipment area. Could there have been snail eggs on the plants... yes but there are absolutely none to be found in the tank at all. I have a plant nursery tank that does have snails. could they have migrated across the room? Strange to say the least.

... how is that possible, you have to have some in the tank right... I don't think they could have crossed the room, but I have no idea why only be in the sump. Pond snails are easy to get rid of though. Either add a few assassins, crush them, or use the lettuce in a cup trick

They aren't in any sealed part of the sump are they?

I would guess you had some snail eggs that got sucked in through your overflow and ended up in your sump.
