will the light penetrate to the bottom of a 24" tall aquarium?

LED are great specifically for deep tanks like that. Shouldnt be a problem getting to the bottom of a 24" tank although I would have to say this fixture may be a little underpowered if your trying to grow any corals on the sandbed. If that isnt the case you should be golden though. LED light usually doesnt start to diminish at all in PAR until 18" of water depth due to its higher focused nature as compared to T5 or hallide which depends on the quality of reflector used to get the light into the tank. This better focus also is what usually will make people say that LED looks very dim in comparison.. which is merely and optical illusion caused by the lack of light escaping the tank thru reflection and refraction, instead being focused more directly down.. in the direction you want it to go.

I have two of the 24" lights. The ends do slide out but I would go with the 30" to get better light in the tank.

I have the 24" light on a 29 gal tank which is also 30" long. It sits on my glass versa top on legs about an inch tall. Provides great light - enough to grow plants and lots if algae. The moonlights are neat ! I think you can use the 24" and save some money unless you need the 30" light to rest on the sides of the tank. The LED lights are the best !

You will want to purchase the product that is the closest length of your aquarium so the lights extend all the way across. If you want the light to only cover the width of your aquarium then yes this particular size will do that. Personally I wish I had bought the longer / larger product. This light works great and supports coral growth and health but I have to rotate it around my tank throughout the day to ensure al my corals get the light they require.

If you want the light to work, yes. Filtration would also be a good option in a tank this small, if its possible.

From my setup, at approximately 60 cm above the bottom of aquarium, the light spread is 60x60 cm. The light spread is greater the higher the fixture is above the tank. A 200x60x60 tank would need a minimum of 3 fixtures. This light fixture is amazing. It's well built, the spectrum is beautiful, it has great depth penetration, and can be used to grow anything photosynthetic. If you're going to grow riccia or glossostigma, use this light in conjunction with CO2 and you'll get ridiculous growth. Keep in mind that this light is very bright, you'll probably have to use the built-in dimmer to dial down the brightness to a level that is appropriate for your plants. Hope this helps.

Mine is 24" deep and it was noticably weak. I went with the double bright eventually and can not say enough good things. 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.

I have it on a 24" deep tank and it lights the entire tank end to end and corner to corner. It's a 48"x24"x24" 120g

The answer is this: the base at it's deepest point is slightly less than 2 1/4 inches; figure 2 1/4 to be safe. (this is the bottom of the fixture)

I have the same size tank, and do not have dark ends. The light distribution is not even, of course, so you will have to plan where to place corals accordingly.

My tank is 17" tall, and the light is so strong I only use it at 65%. I think you would be fine with one at 80-100%

Without knowing how much room and depth you have to place the light, yes, the light will light it up; no sweat. You'll have to play the "light placement" game. Hope it works out.

Hi. I am not sure. I think it would depend on the depth of your tank, from,what I have read.My tank is 24 inches tall, and it works well, but I am also using Flourish Excel for my plants, at the recommendation of my local pet store .I like the the light, it switches from led white to blue automatically, and is easily overridden as other people have noted.So, I can't tell you if it is ok for your tank, it would depend on your plants, but mostly the depth of your tank, due to physics that I can barely recall. There are are online sites you can access for help with the math.I think it mostly depends on the depth of your tank.I do like this light, but, can't give you specific advice. Have fun!!!!

You sure can, I have 2 24" lights 1 on each side since I have a divider in the middle to support the shelf I have on the tank. Really cuts down on water evaporation also. Hope this little info helped you out.

Should be. I originally had my light on a 30 gallon and it was chock full of plants that had no trouble growing under it.

I have the light on the bottom of a 10 gallon tank . And it is works great . It is waterproof for the six inches or so that is submerged. I hope this helps.
