[Polly Plankton]

My tank just finished cycling (5 weeks old), diatoms seemed to be going away and green algae was going away. I have 4 dwarf blue leg hermit crabs, and 2 green chromies. All of a sudden the green algae seems to be taking over - no more needing mowed..it's just flying in the current. I bought a zebra turbo snail and 4 other snails last night and added them to the tank. The turbo snail is just hanging out on a rock and the smaller snails seem to be grazing a little, but not much. The guy that sold me the snails told me they'd probably have my tank cleaned up in a day or two...but I don't think they're hungry. Should I be doing something else to get rid of the green algae? Also...The turbo is just sitting on a rock - should I move him down to the bottom rocks and sand where the green algae is (and how do you move them when they're on a rock)?

I had cut back on lights when the algae seemed to be going away on its own, but now it's flourishing again.

Any help would be appreciated !!
