Lighting Question

[DBLDWNFireMedic]

So... I'm putting together the pieces for my 200 gallon tank. I've got two Rapid LED onyx units and two Mars Aqua units. The coverage for these lights is supposed to be 2x2 each, which should be plenty for the length of my tank (72 inches). My question is if the depth will be fine? The water will be 27 inches deep.

Also, a couple bulbs are out on one of the Rapid units are out. Does anyone know if these are replaceable?

Also, I was planning to run the Rapids in the middle and the mars units on the outside. Thinking of doing a tree like structure in the middle and some regular stacks on each side against the oferflows.

Thanks in advance.

Yea, the mars have plenty of power for your tank. Rapid should be close.

Thanks so much for your reply! Do you think the MARS are more powerful than the Onyx?

I honestly am not 100% sure.

One way to tell is with a Lux meter.

Turn each up to full power and meter them at 12 in.
