Better to post the dimensions of the tank than the brand. If it’s more than 24” than you will need a bigger light. I have 2 over my 36” 90g. |

I just bought 2 Mars Aqua 165w for my new 120g reef. I will be keeping SPS and LPS corals. Just wondering how much power you folks think I should keep each channel on? I currently have both the blue and white channels both at 50% power on both lights...I will slowly increase all to 75% as the corals get acclimated.
Does anyone suggest keeping one channel higher than the other or have any better ideas? Thanks in advance!

I'm building out a custom dual sided tank with the following dimensions: 104" long 12" wide 15" high. I am considering these lights and was wondering if 5 165w or 3 300w would be best? Has anyone built out a long shallow/narrow tank like this? Any recommendations or warnings to these dimensions? I have seen small pico tanks that are amazing with very shallow and narrow dimensions...just looking to have a really long version for myself. Appreciate any and all feedback.

Just be cautious of the hotspots directly underneath the lights has intense par.
That shallow I would build a diffuser You would be able tp raise then high off the shallow tanks |

so if i were to be at a 15" height with a 12" width...how high off the water would you mount the lights? thinking 5 165w units to cover 104" length. Also looking for other similar long narrow and shallow room divider style tanks or suggestions on what could be bad about this setup.

negative is the lack of built in separate timers for blue and white channels. and 2 required power cords instead of one.
I believe viparspectra is the same light but has built in features, 1 cord? I run ocean revive which is similar but spread out leds and built in timers. |

these lights are 16" wide, so 5 evenly spaced would grow anything in your tank
I would have them 15"-20" above the water as shallow as your tank is. I have mine 8" and in a 30" deep tank run 50% but still ramping up percentage with time. |

So I have a 75G (4ft long) and am experiencing sone shadowing with my 2x 165W marsaquas. The secondary optics it has are 60 degrees so I am thinking that that is too sharp and wanted to replace it with 90 degree lenses. What do you guys think?

I tried that but the spread was too much. The entire floor was lit unfortunately

Does anyone have any before/after photos of their tanks with the lenses (or some lenses) removed? I'm curious to see the difference.

Yes. This thread has boomed since I last looked at it almost a year ago. I went with the viparspectra and have 3 on my 180. I run a softie tank so I cannot comment about sps growth etc, but that said these are very good for the price paid. Had no problems with the tank which was previously on 250w MH's.
