What are the dimensions of the lumenmax3 reflectors?

If it was me, I'd be doing a mixture of both halide and T5's. Go with 4 of 5 halides flanked with T5's on the side. I think the 80w T5's are 60" so you should be able to go with 2 80W per length, and at least one row on each side of the reflectors (depending on the dimensions of the reflector and how much space you have left over, maybe 2 rows of T5's on each side {so 4 rows in total}). Or with the 30" depth you could run 24" T5's, perpendicular, between the reflectors. And you could more or less run as many as you wanted that way..

The reflectors are 11''x11'' with 250w bulb. I was trying not to have to make a custom fixture for the lights. thats why i would like to use one or the other. Maybe i could find a good combo light for it that is what i have on my 280g.

Oh ... hmmm, OK then. Guess that changes the advice then!

Hard to say then. The T5s-only option will give you unparalled options for mixing and matching bulbs to your taste. I don't see why an 8 lamps fixture wouldn't be more than enough for 30" of tank height..

But halides do a bang up job too. 5 lumenmax reflectors over that tank would be incredibly sharp.

Flip a coin I guess. Sorry I'm not much help, I'd be agonizing over the choice as well.

Well I finally have some new pics to show you guys. My new sump was just delivered and I can’t wait to get started plumbing now. The dimensions are 96''long 30''wide and 18''tall this should add a lot of volume to my system. I would like to have it up and running before the New Year.

i cant tell from the pictures but is your tank rimless? cant wait too what else your going to do with this monster. keep us updated with lots of PICS.

For the HRV to work do you absolutely need a humid air intake near the tank like you do? Mine tank is in my livingroom and that seems pretty impossible to do in my case.

Humid air sinks to the ground I think so maybe the intake could be behind the tank next to my cold air return?

WOW I shutter to think of what that weighs dry,such a small contact point with the block you'd best be hoping that slab is at least 5'' thick with lots of rebar. Jesus that got to be 8000lbs without a footing I think you should call an engineer or at least do a core sample to see how thick the concrete is.
P.S that tank looks and will look incredible

Hey lastlight

I don't think the intake needs to be right over the tank. I think as long as it is near by it should work fine.

Hey Boomboy

Right now my tank is rimless but the euro bracing is on its way. So not going to be like this for long I hope. Can't wait to get water in it.

Thanks Chris C
