I agree, PO4 @ 0.03 should be a minimum. Coral may be hungry!That 2-4 nitrates and .01-.03 phosphate scares me. It's at least detectable but within range of zeroing out within testing margins. With alk that high, as you mentioned, higher nutrients make coral life easier...but at the same time your par isn't cooking them so to speak. There have been quite a few changes as mentioned so it's hard to pinpoint. My advice would.be to bump up those p04/n03 numbers a bit (maybe .05 p04 and 10 n03 at least). Personally, I would get for at least .08 and 15-20. More experienced reefers may have a better answer.
But, I will say, some don't agree with me.
Phosphorous and nitrogen (ammonium) are preferred. So as long as you have a constant supply (FEED YOUR FISH) OP should be okay.
