I’m planning a build for a UNS 90LA. The dimensions are 36x12x12 and the display area is 31x12x12. I was thinking an AI Hydra Edge 44HD, but am open to suggestions. I might be able to swing a Hydra Edge 68HD for better coverage and less shadowing, but that’s pushing my budget. I don’t want a 30” light bar.

It will be mixed reef, but not many demanding SPS. Mostly LPS. My main goal is coverage and less shadowing.

Let me know your thoughts.

Thanks.

Why did you pick those particular lights?

Your 20 gal approx tank with the shallow and narrow dimensions is really more suited to bars..but anyways
And since you are going "not demanding" your wattage really isn't more than like 40 watts total. Not 400 :)


Case in point 2 Nicrew Navireefs has a total wattage of 130.
and if you can get the deal $180 (add another $50 for the controller)
So $230 and you have 2 pucks one can spread out for better overall coverage.
No fancy phone app or world wide cloud control but hey..they work.
Even at $280 for 2 you approach the Hydra 44 cost but have the advantage of a more even light spread due to 2 independent pucks.
44 spread..
