I'm being overrun by snails, killing nearly 30 a day right now

I think I'm starting to notice the eggs they're laying at the water line (little white dots) and I'm cleaning them out before they can hatch. If things dont start improving, I'm going to have to change my stocking plan and find something that eats snails aggressively, but I'd rather not do that. I hope patience and vigilant snail hunting will finally pay off.
