I guess I've been paying too much attention to the new shiny 75 gallon reef and I'm having some issues in my 37 gallon. Lighting is from a 150W metal halide and a 24" T5HO blue. Regimen as far as maintenance is a five gallon water change every other week. (I can't seem to be home long enough to get back to every week as I once was.) Circulation is provided by two AquaClear 301 power heads and a MaxiJet Pro 600 set up as a circulation pump. The return pump is a Mag 5 and I have a Coralife 65 Super Skimmer.
Mobile livestock includes a fire clown, a coral banded shrimp, some blue leg and scarlet hermits, teo large turbo snails and three small ones.
I also have a long tentacle anemone, derasa clam, three varieties of mushrooms (blue & green, red, and green hairy), some green star polyps, a candy cane coral, and some xenia.
The nem, clam, and candy cane seem to be doing fine. My issue is most noticable with the GSP, green hairy mushrooms, and xenia. The GSP isn't opening up like it used to and looks to have green algae growin on the mat. The green hairy mushrooms look so small to be mistaken for individual zoas. The xenia won't extend its polyps and looks pretty much just like brown strands at first glance.
Paameters are as follows:
Specific gravity = 1.024 (refractometer)
Nitrite = 0ppm (API liquid)
Nitrate = 10ppm (API liquid)
Calcium = 440ppm (API liquid)
= 10degrees dKH
/ 179ppm KH
ph = 8.0 (Salifert)
Magnesium = 1360ppm (Red Sea Pro)
Phosphate = 0.25ppm (API liquid)
Here's a pic of the test results in case my color perception was off:

Any insight is appreciated!
