So, @reefwiser, do you think that going back to the dosing amount that had my corals looking their best is tilting at windmills? I will be reducing the amount by almost 50%, and if it is Alk burn, shouldn't that help?
I am also keeping everyone else's suggestions in mind, but I only want to change one thing at a time so I don't mess anything else up. I've found changing too many things at once rarely solves the problem and only left me more confused about what I needed to change.
Your lfs has an sps 40 gallon cube with a single hydra 26 hd?
Ok. Is it the exact same size/model and just a single fixture?It's a mixed reef.

I'm using one AI Hydra 26HD. The Acro is 9" below the waterline and the light is 9" above the waterline.
The OP nitrates are .2-.5 and po4 is 0.02 and already using nopoxlower light intensity and do water changes and/or add Red sea PO4 (same as vodka dosing to reduce Po4)
I get my RO/DI water as well as my salt water from my LFS. It reads 0 TDS.
I have reduced the amount of NoPoX already, and will slowly try to wean my tank off of it.
I've looked around locally for a PAR meter with no luck. My LFS uses the same light setting on their Hydra 26 with the same tank and have great Acro growth in their tank.
Hi IslandLifereef,
I do have a par meter and I’m in San Jose.
If you’re nearby I can lend you mine!
How about the Magnesium level? seems no one asked or mentioned.
How many watts is your ai setting during its peak time?
Tony Rogers tank is way bigger and deeper.It draws 73 watts at its peak.
Here is a link from AI with a successful light setting with UV higher than mine.

Check out Tony Roger's settings.
Would you mind sharing your light schedule @Chaswood79?
Thanks again.
Btw I checked the par using your settings with my 2 hydra 52s turned down to 100 watts, meaning 50 watts per fixture. Par at 9” below the surface was about 125-150.Tony Rogers tank is way bigger and deeper.
