I have a 72 gal Bow Reef Tank and a 120 Gal Reef Tank they are both 48" is one light enough for each tank both have T5 right now with 6 bulbs

No. I had to add 4 t5s with my current usa to my 48 inch 55 gal. to keep my lps's near the bottom happy
143528
No, I think you need 2 I have a 90 gallon 48x18x24. The lights are only about 3 inches wide So you probably need 1 in the front and 1 in the back. My corals responded immediately to the lighting. I only have soft corals

I'd go with 2 on the 120 (its the 2' X 4' X 2' right?) I plan on using 2 for my 120 when I get it set up. on the 72 bow, I have one on my 55 and it works fine. I would assume it would be plenty of light on the 72.

This light is very bright. I had to put it on the lowest light cycle it has. It is the best light I have ever owned and you'll never have to change bulbs. What more can you ask for. I've owned it for over a year and still love it

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.

I would say yes and maybe too much light depending on coral and what size you are using. I have 1 on a 100 gallon soft coral only and it is enough.

I would say yes... I have two on a 55g tank.. It's 48long...turned to about 50%. I also have a 60g cube... It's 24x24... Have one on it and one is plenty! And a 125Reef with 3.... I have the LEDS turmed up about 75% they are BRIGHT!

Im running it on 75Gal (21" deep) I get low light at the substrate at best. I've said before to get medium light I would need 4 of these on my tank.

They are real good lighting quality and powerful class. at least for my aquarium 55 Gall. is excellent. my corals are growing. I summarize very simple: I have NO complaints. 02 I and my aquarium lamps REEF is fine. (Yourself can graduate the brightness of the lights). It is very easy

This 20 inch fixture works great on my 16 gallon bow. I also use 2 of them on my 60 gallon cube, and I am buying one right now for my 26 gallon hex. I use a 15W 18 inch Life Glo T8 bulb, which is by far the best bulb I have found to grow plants. The plant plus LED on my hex doesn't grow the plants, only algae. I also have a 24 inch Life Glo bulb on my 35 gallon bow that grows plants like crazy--I use the trimmings as new starts. I like to trim them down 6 inches below the top, then when the stems split and grow up, you have multi-stem starts instead of single stems as sold in the LFS.

I have mine on a 72 gal mixed reef, soft, lps and sps corals. I run the light full power, blue and white...everything seems to thrive.

If it is a 40 breeder you would use the 36" fixture. But in either case, yes. These lights are fine for a coral tank with the 3 color lights and wattage you would be generally fine.

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.

No. I had to purchase a T8 shop light fixture (Home Depot) to replace a T5 version I had on hand. I use it over a 90 gal. Aquarium in which I keep an adult female yellow bellied turtle. She's healthy and is still growing every year. I replace the bulbs every year. Good luck.

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.

You would need a stronger lite for a tank that size of you wish to have corals . Fish only might be ok

It will fit 24" long tank or longer. But light just has 17.75" long, I don't suggest you to use it for your tank. I use it for my 20 gal plant tank so it protect fit. I mean light is bright enough to keep my plant to grow. If you use it for plant tank, the one 24" to 36" will be better to you.

I assume so, since that is the cube that comes with the 5 gal. tank. Beware though, the lights don't last very long. On mine the lights burned out quickly. The center bulb after only about 6 mos., and the rest shortly after the warranty expired. Guess that's par for the course nowadays. They could make the lights replaceable, but instead one has to purchase a whole new cube for $50, which is about 40% of a new one. It's a nice tank, but unless and until they have replacement lights, I would not recommend buying one again.

I only have a 29 gallon and my tank is loving the lights. My personal opinion is that it would be better to run two with a 60 gallon. Current is great though. You will love it!

That is completely up to you. If you are planning on getting a longer tank, I would go with the 24-36". Also, with the 18-24", you will have 3" on both sides of the tank that will rely on light refraction and light angle to get light. In my personal opinion, get the 24-36". This way the tank will get the most light and help the plants.
