SPS not growing/growing s....l....o....w

So..........some of the SPS really didn't appreciate the drop in Alk and I saw some STN in a couple of pieces from the swing (montipora setosa & the tri-colour valida).

Chemistry is nailed down and params have been stable for the past week or so at:

T=78.0F (raised this over the past week)
S.G. = 1.026
Ca = 475ppm
Alk=8.75dKh
Mg=1400ppm

I've increased my feeding to either 1cube of spriulina brine + 1 cube of cyclopeze or 2 cubes of spirulina brine/day. 1/6th a nori sheet every other day. Cultured phyto 2x per week. In hopes to raise P04 to detectable levels.

My dosing of amino Acids (currently using AV Fuel) has also been kicked up a notch. They recommend 13.5ml twice a week for a tank my size. I've been dosing 7ml daily. Again in hopes to raise P04 to detectable levels.

I haven't noticed any negative effects but I also haven't had to scrape the glass at all in nearly two weeks which leads me to believe that I may be starving the corals.

Thoughts?

I know this sounds crazy but could my bioload vs skimmer be too small?

Best way to raise the P04? (I've had suggestions of more amino acids, more meaty foods, Reef-roids or just more fish.)
