Another trip to the LFS today!

Picked up six more turbo snails and a cleaner shrimp. I just like the look of the cleaner shrimp

My battle against the green hairy stuff is looking pretty good! The red algae problem I had is also gone with the tide!
I recently purchased a Red Sea Reef Foundation Pro test kit (Calcium, Magnesium and Alkalinity)
Here's my numbers:
Calcium-520ppm
Alkalinity-9.2 dHK
Magnesium 1440 ppm
Working on bringing my alkalinity up to about about 12 at the moment which from what I've learned should bring my calcium down...right?
My frogspawn has not been terribly happy since about a week after I got it. Polyps are extended maybe half way (if that). I give it about a week in one spot and then move it to a different location in the tank to see how it likes it, but still no luck. Is there anything in specific that I could be doing wrong? I have him in a fairly low current location which, as far as I know, is what they prefer....
