I’m running 2 Hydra 64 on my 90. Not sure I love the results. Some things don’t seem to be growing or barely. Ie GSP looks healthy everyday yet hasn’t grown in about 4 months.
Colors don’t seem great in particular the blues on my coral. Look good when buying.
Does anyone have a good AI schedule they can share? I think you can share from AI App.

I use a slightly modified version of Saxby's program which you can download from AI site.

Good luck, lot to choose from

Something tells me it is more than a lighting issue. What are your parameters, maintenance routine, what do you feed, what do you dose? What types of coral are you keeping other than GSP? Those lights could be overkill for a lot of stuff. How high are they mounted over the tank and what are your current settings?

I run this schedule on my mixed reef 120 with two Hydra 26HDs which are significantly less powerful than yours and have 3D Reefing diffusors on them. Recently added on Actinic Vitamini strip as supplemental as acros were growing out. But the tank ran great with just the Hydras for some time. Here’s some recent shots.

I’m going to try Saxby for a while.
Also moved a couple things to see if a different flow helps.
Also sending out ICP test.

My main parameters are within suggested tolerance. Maybe Nitrates too low? See attached. I am not dosing yet. I do feed reef roids 1x per week.
My lights are not turned up as high as yours. They have been giving about 250 at the top and 150 at the bottom with Pat meter.
might just be expecting too much.

I would say nitrates can definitely come up, but every system is different. I get best color around 4-8ppm nitrate and .07 ppm phosphate. Your par readings are very similar to mine despite settings. About 280 on top of rocks by acros and 100-140 on the sandbed. My lights have half the pucks and are a generation behind yours. If your nutrients stay as low as they are and you crank your lights up even more, there is a good chance you will see bleaching and paling on everything. Just take it slow and try not to make any drastic changes.

Another question is the age of your system. There is something magical from a bacterial and microfauna maturity that happens around a year after setup and everything just seems to do better for me. But no hard and fast rules.

Thanks. Only 5 months in.
