Scott's 270g aka Project Mayhem

So my RR sps are showing up today and here are my test results from this morning:

Mg 1350, Ca 400, Alk 7.9 dKh, phosphate 0.04ppm, Nitrate 0.2ppm, s.g. 1.025

My apogee meter showed up and I will start testing today or tomorrow

I also picked up a couple nice chalices and some zoo's from the LFS. They are sweet!

Details:

Mitras 6100HV running in High Efficiency mode with max output at 80% (brightness set to 70% in Light composer)
Initial PAR numbers:

~280 at water surface (9.5" from lights)
~150 9" down from water surface
~80 20" down from water surface in somewhat shade

Mitras 6100HV running in High Efficiency mode with max output at 100% (brightness set to 95% in Light composer)

~480 at water surface
~250 9" down from water surface
~120 20" down from water surface in somewhat shade
~150 on bottom of tank

So the important question is do you think bringing up the average PAR values by 50% is a bad idea? Seems a little drastic to me. I am thinking maybe dial them back to a 25% increase and see how things react and then go back to the 95% brightness. Suggestions, opinions, etc?

I went ahead and dropped total brightness down to 82%. That put the PAR numbers all ~25-30% higher than original. I will see what response that gets and then go up from there hopefully. The whole reason i want to go up is from the reading I have been doing on PAR values around some of the SPS I'd like to keep.
