Would this work on my 90 gallon tank that is 48" L x 18" W or do I need two of these lights?

Will probably work fine my 55 I only burn 1/2 the lights and coarls are good

I have one fixture on a 75 gallon tank and it is more than enough, but my tank isn't as deep as a 90 gallon would be - the water depth is probably something to consider too. I have LPS, SPS and soft corals and they are all doing well (too well in some cases). If you are only going to have fish and/or soft corals then I am sure you have plenty of light. If you have a lot of SPS all over the tank you MIGHT consider a second, but only if you have species that need a large amount of light. If I had to chose, I would buy one, then see what it looks like.

What do you plan on keeping in the tank? If fish only and leathers then yes but if you plan on keeping sps or LPs corals then no I would buy something else

It should work. I have a 48-inch and a 24-inch light on my 125-gallon reef tank with several types of corals and an anemone.

It will work. I have it on my 75 gallon. It's not as good as my halite but it is good for fish and live rock.

24-36" because you want the LEDs to span the length of the tank. You'll have darker spots on the end with the 18-24" light.

Is nice cause it is programable.It is adjustable on hight and had a ring attached. I made my own light hanger,from the side wall,instead of the ceiling.Hope this helps.

I have only one light on my 72 gallon bowfront (48" long, 24" deep) and it looks great; however, the far sides are not brightly lit. My corals are doing very well but I have softies, zoas, mushrooms etc. Two lights would be ideal and I would imagine a necessity for sps corals, clams etc.

It all depends on how bright you want it. I have a 26 gallon tank and got 2 bulbs, but it makes the tank really bright. If your tank gets quite a bit of light from a nearby window or something, I think 1 bulb would be enough. Why not try it first with one bulb and if it's not bright enough, buy the 2nd one?

I have mine on a 90 gallon salt water tank and it pumps out more than enough light

I have 2 48"-60" on my 90 gal discus tank and I love them, I would recommend 2 or 3 for your planted 125gal tank, depending on how bright you want it.

Depends on what you have in the tank and the length. 4 foot wide fish only two 24" light pack will do. If you have coral you would probly want 4 24" minimum. High lighting coral need 3-4 watts per gallon. Most coral 2-3 watts per gallon will do.

assuming this is a freshwater planted tank, the good thing about hanging fixtures is you can adjust the height of the fixtures. I would saying having two would be ideal, and give an even amount of light over the entire length and depth of your tank. having only one would give you enough light in the tank under which the light is positioned. but having two would give you more even light over the entire tank. Unless you want to create different sectors of your tank for low light and high light I would use two. With two you can still create those different sections, by adjusting the height of each fixture, and also give you the ability to change different areas of the tank any time you want. assuming this is a freshwater planted tank, the good thing about hanging fixtures is you can adjust the height of the fixtures.

I have a 60 inch 110 gallona q and have one on mine. It gives off bright light....my tank does not have live plants... So may want to be sure this is the right light for live plants.

The daylight bulb is 10kk the night one I don't recall, I can tell you I had this on a 90 gallon aquarium and it lit the tank very well for my needs, I would hesitate to use this if you have live plants in your aquarium though.

The light strip comes to within two inches of each end of the light fixture. You'll want the 48", since two 24" would leave a 4" gap unlit in the center, plus wouldn't look as sleek and clean as the single fixture. I have them on both of my 55-gal tanks, and love them. (The center support on my tanks don't interfere with the light, since it sits slightly above the top of the tank.)

That will probably be most dependant on what you have in the tank. The LEDs are pretty bright and can most certainly light up a tank of the right dimensions.

I have a 100 gallon cylindrical tank 18" x 72 " works fine very good lights, even illumination, intensity adjustable, can do white, or blue light or combination, and moon light

My system came with 4 panels. My tank is 100 gallon with a 5 foot by 18 inches footprint, covers everything pretty good. Yours being 180 gallon, may have a larger area to cover and leave some areas in shadows. Now my lights are resting about 1 inch above the tank, so maybe if you suspend them a distance above your tank, the light may spread more. For my 100 gallon, perfect, for 180 gallon, I couldn't say for sure.

No you will need 2 lights, to light up the entire tank for corals to thrive.
