Sps coral colors

[Mikenroe]

Hi there, I am getting my tank more SPS dominant but still have a mixed reef with some LPS, Softies, and a few NPS I have AI hydra lights. I do a water change twice a month roughly to every three weeks. I supplement daily with alk and cal and mg weekly. I also use the rscp coral color supplements and follow the recommended guidelines for that. I feed daily Larry's reef frenzy and twice a week I use reef nutrition to help with the few filter feeders I have like the feather star. However my question is this I am wanting to get a lot more growth and color out of my corals. Anyone have good suggestions for my ai settings, using the director, to achieve this. My aquarium profile is below. My water parameters are as follows:
Nitrates - .02, po4 - not sure, Alk - 8.6, CA - 440, Mg - 1350, Potassium - 420, Iodine 6.3. Thanks in advanced for any suggestions. My tank is pretty standard length.
