I run it 100% blue and around 75% white on both of my fixtures and my vega's the same. 120 gallon deep dimension with screen covers on it no glass with the fixtures sitting around 15 to 18 inches from screens

I'm running this fixture at 50/50 on a 54 gallon corner tank about 10in. from my tank.

Point the pump at the glass, not down and that should help. .. I have 2 on my 29 biocube and have no issues.. A 240 is not enough in a 20 gallon if used alone so I would at least pick up another 240 for the opposite side .. Do you have enough rock or is the flow getting obstructed down ? Mine are placed mid level in tank and again are pointed at side glass

Only low/med. light corals will thrive. I use it for qt tanks. Yellowish tint; the actinic isn't that noticeable. Very bright for such a small fixture however.

My lfs has a comparable model. They recommended 6-10 in. Mine are about 6" from the water, I would adjust the height to get the correct spread and then adjust the brightness accordingly. In other words the higher you hang the lights the higher you should start your intensity

On the 36" each bulb is rated at 39 watts. So the 4 bulb fixture is a total of 156 watts. Dont get to hung up on watts per gallon per say. It does matter, but look into PAR more importantly. With my 36" I have no problem growing anything. (SPS, LPS, etc...)

You can run 3 under water and 5 above. I think it's better than 20 watt halogen bulb.

I'm running it in a 90g saltwater fish only. light output is fantastic. But I don't know about grow capability. My local store is selling this for $350.

Hmm...I dont know. My bottom is plastic but looks great. I dont know where any glass is other than the bulbs. I do love this light all said and done.

Well its not giving us much information about spectrum but lumen level seems a bit lower then I would like, Using a fixture like this then I would stick to low to medium light level plants, if the mediums die out then you know you need to stick with low light level plants like java fern and anubias. Also depends on how deep of a tank you have. Try a few listed above, Would not buy a lot to try as they might end up dead.

My 24 inch long is exactly 24 inch , I have a 55 gallon corner aquarium and it looks incredible, I do run 3 bulbs in it , the blue colored light for it is great and the night time light is perfect for fish , I would get 48 inch if it fits on your glass . 2 24 's would not look neat to me on top

I have 1 unit on my tank which is 3' wide x 2' deep x 2' high. one light is fine; the edges fall of a just a bit but for a 6' tank should be good with 2 lights. I have it set to only to 65% at the highest as the light is brighter than my old T5's.

The bottom of the fixture sits approx. 1/8 of an inch above glass top. The top of the fixture sits 1" above glass top.

Depending on how high you mount the light above the aquarium and how intense you want the light to be can determine how much coverage you need. If you aren't growing corals that need a ton of light, 1 light would do probably mounted 10 to 12 inches above the aquarium I would guess.

36" or some plants will not grow well and the tank will be unevenly lit. You always want it pretty close to the tank length if you are using plants with your fish. My tanks have plants everywhere because I give them light and it not even very bright either.

Yes, my acrylic 120G that I currently have this fixture on is 24" tall and it does a decent job lighting. However I cannot comment how well your foreground plants would do, since all my plants are potted and I have shorter plants setting on rocks to add height.

I use to used 2 of these for low light plants on my standard tetra "55" g tank (its actually more like 48g and mis-sold as 55.. but I digress) the 24"-36", it has 4 rows of lights that only cover about 17.5" in the center of that 24" space, the 36" is just max leg extension. I removed one leg from each light and put the de-legged side on the center brace (I put a 1" bar on top of the brace to keep lights level), pushing the 2 lights together they fit snugly on top. It worked well for low light aquarium plants like anubias , java fern, vals, mosses, and marimo. However if you want medium light plants I'd strongly advise a different brand made for plant growth.. or just get 6500kelvnin cfls bulbs and clamp on lamps (3-4x) if you don't mind the look of them. I've upgraded to a 2 bulb 6500k t5 light over my "55"g now.

If you have an all glass top you could get a 24, though it wouldn't be stable sitting there. Assuming you have an open tank, you can either get a 30, or 2 12" lights. The 2 12s would certainly be more costly, but might give you more control over the light output.
