Quick question, I am going to be purchasing a 180 gallon tank and was wondering if these lights would work. I would be going with the 300w, my question was will 2 of the 31" lights be enough to light a 180? Or do I get 2 31" and one smaller sized one?
2x 300w and 1x165w would be ideal for that tank, but 2x 300w with optics removed would cover your tank at minimal...
So I messaged a seller on eBay about the Mars aqua lights dimmer and got this response. Anyone bought one recently and know if this is true? Want to connect it to my apex but I thought everyone had to use the converter to hook it to their apex.

I getting ready to mod my 2 - 165W units. I am gonna swap out the 3500k with 20k and the 7500k with 460nm blues and UV violets.
Do the red and green provide any value?
If no, what color would you add? 20k, 460nm, or UV violets, or something else?
BTW I have a LPS dominant tank, thanks.

Hi, I'm new to the forum and have read most of the posts in this section. My tank is 60"x24"x18" and I was thinking of using 3 of the 165W lamps turned sideways and about 9 inches apart. Since the lights are 15.7" and my tank is 18" across, I thought this would work. 2 of the 300w lights would be too long.
One other question is about installing them in my light hood. It's entirely enclosed and the lights would sit about 7 or 8 inches above the water. Would this work? Would things get too hot? Would I need cutouts in the top of my hood for ventilation? Any thoughts on this would be much appreciated. I am going to have soft corals and some fish in this tank. Thank you.
I personally wouldn't bother with the PCs. Bulb replacement and heat would turn me off
