Is this AI Prime too high off the water?

[laezur]

yo!

Just wanting to make sure I don’t have this thing mounted too high or too close, trying to evenly distribute PAR - don’t want it all in the middle.

Height looks ok, putting a PAR meter on it will tell you best. I have 2 AI Primes mounted about 9” off the water and about 5” apart.

I’d love to but don’t have one to hand and those things are expensive, don’t think my LFS rents them either

I tried to go off BRS specs for the same tank that I have to get a rough idea of where PAR should be

How "tall" is your tank? Could factor into the light hitting the sand bed for any corals you want to keep low, plus how high you have your aquascape for any SPS you may want to keep.

I believe around 8 inches is standard height to have it at.

Mine are 9 inches off the water, with a depth of 21 inches.

BRS has done a video where they test pars at different height for different size tanks, with AI Primes 16 HD. You should really watch it.

It’s a Red Sea 170 so I believe 20”
