Would love to know what everyone is lighting their 120g 4x2x2 tanks with. Picture of my tank attached. Looking for something with enough spread if I don't mount them more than 12 inches from the top of the water. Have had a tough time finding something that can cover 24 inches front to back wall to wall coral.
For the last 5 years I have been running 4 x of the Chinese black boxes. Growth is good, but to say color is not great would be an understatement. I have tried a couple different lights already over one side of the tank:
1) Tried Maxspect Ethereal 130W which was absolutely pathetic in terms of coverage and strength. Manufacturer says 24x24 coverage but in reality its more like 16x16 coverage and not strong enough for even halfway down the tank.
2) Tried two of the AI Hydra 26 over half the tank, and while they were strong enough to keep the zoas happy on the bottom the spread was very poor. Mounted about 12 inches off the water with both fixtures combined you are looking at covering a 24 x18 area max. Plus the cost would be outrageous for 4 of them.
In an attempt to keep this organized and relevant please only respond if you have a 4x2x2 and have had the lights running for more than 6 months.
Thank you all in advance for any info you can provide.
