Those with 30"/36" deep tanks (Lighting question)

[cstires]

I'm having a tank built that will either be 30" or 36" deep. I want to light the tank with metal halide and reefbrite LEDs for the actinic.

What fixtures are you all using to get the proper light spread for those widths?

Thanks in advance for your help.

My tank is 30" deep but I am using LEDs, cheap Mars Aqua ones. SPS grow under them and have great color.

I've had LEDs in the past and just never was pleased with the growth rates. I had Radions. This was probably 5 years ago or so though.

I'm not totally against them, but I really like the look and growth rates I had gotten from my MH's.

I ran MHs years ago with out issue. Radions will work great for you. I would say 400 Watt is what you will want

I'm using same fixtures at 43" deep tanks. Again great growth and cheap

Have LEDs on my 27 cube, have no issues with growth or colour but getting the right power settings can be difficult with a deep tank, top will be very bright, bottom very dull. That bring said mine are currently at 15% white and 80% blue and will nuke new corals if I'm not careful in where I place them.

Also worth mentioning that 400watt metal halides will put out a crap ton of heat so hope you have a decent cooling system in place.

When I said deep, I meant width. The height of the tank will be 24". Just wanted to make that clear so we were all on the same page.

How is the ease of setup on those Mars units? Are they similar to the EcoTech Radions?

I do love the fact that LEDs don't produce heat like MH's do. I just want to make sure they'll be able to give the spread I need and provide the correct light needed to make SPS grow like my MH's did.

Don't have the Mars unit but something similar, very easy to set up with remote, bit of pain in the *** with the control knob on the light unit.

Pic of the tank to give you idea of the light spread, excuse the glass needs cleaning.

And what are the dimensions on your tank?

I am currently working on a build that is 72x45 deep x 30 tall and went with 6 radions and my tests have come out good so far. I will throw in that you should always go with the bigger size ��.

Tank is 36" deep. Have four aquatic life halo led fixtures , two 165w BML led strips, and two 150w 6500k outdoor rated led fixtures (They were like $75 on Amazon). Here pics without the 6500k fixtures:

How did you space them out? My tank is looking to be 48x36x24. I'm wondering if 3 would be enough to light it?

Is your tank bare bottom? Or just a dusting of a sand bed?

It's not up yet, but I think I'm going to go with sand this time. It just looks more natural to me.

I have very similar lights. What are you setting the blues and whites at, and for how long? Growing SPS with those is impressive!

I have the ATI hybrid 8 bulbs for my 30" deep tank. Works great. I have the T5 on 70% and LED on 30%.

Water line ~450 - 500 par
Mid tank ~300
Sandbed ~180
