165 gal, 72" width - Need lighting suggestions
I have tried a number of lighting setups, but can't get it right. The usual issue is not enough light. I mainly try 2 x 36" LEDs, but they don't sit right and never put out enough light. This is for a FOWLR.
Any suggestions? |

According to the coverage, I'd need 3 of them?

That may be by listing a minimum wattage or by at least letting us know specific fixtures that you have tried in the past and we can try to deduce the amount of light you want based off that.. You should also let us know if you need fixtures that hang or those that have specific mounting legs to allow them to fit on the tank and if do did that happen because your tank has a center brace that you used or if you fabricated something to hold the center legs or what.. Or just go all out and as stated get something like 2 of the 165W black box LEDs on Amazon/Ebay (Viparspectra/Mars Aqua,etc...) or one of the 300W varieties.. I would argue that both of those if run anywhere near full power are way more light than a FOWLR tank would need but luckily those are fully adjustable (and you certainly wouldn't need 3). My 72" 120G saltwater tank grew corals like crazy with only 2 of them and the amount of shadowing (dimmer areas by the edge) was very..very minimal (not really noticeable).. There really isn't much in between.. Its either the low power .5W LED fixtures like you have likely been trying or 165W/300W fixtures.. Those black box LEDs 165W/300W are typically fixtures intended to be hung from the ceiling or require you to fab up a mount..

I've tried the flat LED systems that I lay on top. My tank just looks dark and not very appealing as is it now.
2 of the 165w would cover a 72" tank? I guess I could hang them from the ceiling, but not crazy about that idea. |

If you are somewhat "handy" you can easily whip up some mounts to avoid handing..
I just used some aluminum angle to create some simple mounts to go across the tank (sorry I don't have pics anymore I don't think).. But it was just 2 angle pieces across the whole length and then 2 pieces horizontally for each light to create a "pocket" that each light sat into.. Aluminum pop rivets held it all together.. Quite simple..

https://www.ebay.com/itm/Beamswork-D...item5fcaa4ec03 Personally I'd suggest 2 but?? Note they have a tendency in 72" to bow in the middle a bit..not sure if they "fixed" this or not but it's only look. 72" DA 180 176x - 8000 lumen 144x 10000K, 32x Actinic There are "add ons" to color it up a bit.. like one of the above and one of these: https://www.ebay.com/itm/Beamswork-D...item8992669ee0 Of course total is like $130 About THE cheapest efficient option I can think of 2 are only 10.5" wide.. 2 Chinese "black boxes" are about the same price but using 1 to cover 36" is asking a lot, even with the lenses removed.. and of course you need to hang them Hang them high enough to cover left to right and you'll get a lot of spill out of the tank front/back.. Color Taste is very subjective so I can't make that decision. Beamsworks are fairly ignored in the reefing world but effective in the fw one for usable economic lighting Https://youtu.be/GW4fhrKZiLI IF you are going "deep blue" than this isn't for you.. Look to some Orphek strip lights. Last edited by oreo57; 07/16/2019 at 03:23 PM. |

I think I dropped $210 on the 2 lights. They have timers and fully adjustable intensity. I think you'll like them and if you ever want some coral you'll already be setup

2 of 32" Pro Timer SB Reef Lights would be perfect.

700+ watts of LED/$620+ for a fish only tank?
If they want corals then ok but for fish only thats crazy IMO..
