Best algea eating snail?

[reeferaddict]

I'm actually a little surprised at how few clean up crew the respondents so far seem to keep. I must have close to 75 snails... 10 quite large Turbos, 30 or so Astreas, 7 sand sifting snails, 4 rock snails, and at least a couple of dozen Ceriths that I can recall off hand... they all seem to go everywhere, though the Ceriths hide in the sand until the lights go out. Sometimes keeping corals in place is a challenge, but epoxy helps. I'll not forget to mention I also have dozens and dozens of hermit crabs and other detrivores to keep things clean. My recent bout with hair algae was more about high nitrates & an old test kit, I could only imagine how quickly the tank would have been overgrown without these guys on constant patrol! Oh yeah... my mini Tang school keeps most surface algae in check too...
