I did an experiment once where I had a small pond (300 gal??) that had string algae and I moved snails form other ponds into this one pond to see if they would have any effect. They didn't, at least that I could see. The pond filled completely with string algae.

Now these were the best snails probably, just small things I had. But it was the first time I really measured growth rate of string algae (at least this one species). When I finally removed the algae the total weight was 97 lbs. What kind of army of snails would I need to eat all that. Now I realize that's not really true. In theory the snails would eat the algae as it started to grow so it would never grow much. But still, seeing how fast algae grows I think you'd have to start with a lot of healthy snails. Coming out of winter, cool water, I assume the snails what be a little slow (er than normal). Their numbers down from winter too. My money would be on the algae winning that race.
