Hey orcus not to go off topic, but I have to ask. My lfs tank has 40ppm nitrates and its stacked with corals to the brim, with everything. I am just not sure if 25ppm could cause such an issue with corals. I tested the water, 2 different stores tested the water, mag is little low 1280, but I don get whats going on. I am waiting to see if it's a phosphate issue with hanna checker because red sea and api sucks. I buy the ro water from the store so not sure they use that water in the store. So I am really baffled with my issue. Should I dose some coral color from red sea. Maybe I am missing some trace elements?
Hmmm the settings should be perfect for the Red Sea tank. Are you noticing anything that is leading you to believe you are having PAR issues? Are corals, nems or clams reaching for more light? Always be mindful that the the schedule is very heavy on sub 550nm spectrum. The human eye is absolutely terrible identifying relative intensity of light at this wavelength. What I am trying to say is what looks dim to you may actually be intense for your corals

Gosh dang do I love the AI Hydra 26HD's!
I've been meaning to post my PAR readings on this thread, just kept forgetting to lol.
My Reefer 170 is running a single AI Hydra 26HD with most SPS in the tank. The only other type of coral is a colony of Gobstopper Palythoa's that are on my sand bed in the far left front corner. I'm using the mock Ecotech Marine SPS AB+ profile that Orcus created a while back.
What do I think of the profile? It's amazing! I literally notice growth on my Acropora every 2-3 days. I cut a frag off of a Millepora colony just to test and see how it would do. Within the first week I noticed tissue starting to quickly form. Today, it's starting to form branches. This cut was made about 3-4 weeks ago now. The frag itself is starting to encrust over the glue as well. I'm really really impressed with the lighting schedule. I even sold my dad on the AI Hydra 52HD's he's now running over his 210 which replaced his Metal Halides and loves it.
This is the profile Orcus provided us with the settings as the AI Hydra HD placed 12" AWL with the peak settings as follows:
Tank: Red Sea Reefer 170 24x20x20
----------------------------------------
Violet: 80%
UV: 80%
Royal Blue: 90%
Blue: 90%
Green: 25%
Deep Red: 25%
Cool White: 25%

I totally need a PAR meter, which one do you use? BTW the tank looks awesome!!! I am glad the schedule is working so well.

Did some rearranging last night I'm really loving the 24x24x20 dimensions!!! Also now im really curious as to what my PAR reading are because I run a hydra 52hd AND 2 Prime HD's and my tanks the same dimensions as your haha

How's growth and coloration with those settings? Thinking of picking up 3-4 52 hd

72" by 26" by 24"
Havent purchased the lights nor has the tank arrived. So I have not even dipped a toe into the AI hydra playbook. I'm sure I'll end up with 4.
Ok guys, I have a question I haven't been able to find an answer to. I have a shallow rimless (48x24x18 tall) I have two Hydra 52 HDs about 12" above the water. My question is in regulates to power/ percentages. All of my blues peak at 50% for most of the day. But how high could I go on a tank that shallow? It is an SPS dominated tank with just a few LPS sprinkled in and some zoas. The issue I am having is I know it's a lot of light. Some mushrooms I had bleached out under them except for the ones under shaded rocks. My acros all grow very well and have good color. However my zoas which are low in the tank seem to be stretching like they aren't getting enough light. Anyone else run into this problem?
Here are my settings![]()

And here is the tank

The top of the rocks are just 6-7" under the water surface.
Any info would be greatly appreciated

I have yuma mushrooms growing very well under the lights using your lighting scheme but it's a hit and miss with some regular ones.Finally, I honestly have given up on mushrooms with these lights, I can't grow them. Zoas though seem to be thriving and growing very well. Beautiful tank btw, I LOVE the dimensions.
