Okay, I solved my snail problem!! I removed every piece of driftwood, scrubbed it good under running hot water to get all the snails and egg packs off, rinsed them in "good" water, and replaced them. Then I added 2 loaches, a Zebra and an Angelica. Within 2-3 days, I had a hard time finding any snails. Just their empty shells floating on the surface. I hope the loaches last, they're doing a Great Job!
