your tank should be ok with standard turbos.. i didn't know there was a difference between the turbo snails. you don't need more than 2-3 for a 30 gallon IMO.
sometimes i will pick tem up, and place them on a patch of algae and they will clean it for me. they're not always driven enough to cover every surface.
