Diatom dieters?

[Scavenger]

Well here I go on my cycle of algae blooms after 3 weeks of setup.
My question is, whats a good eater of diatoms? I know it's all part of the natural cycle, but wanted to keep these little buggers in check and not have a brown tank. Is there a good snail or crab for these unsitely little guys??

thanks.
