93 gallon rimless cube build

I've seen gorgeous sps tanks under all 3 major lighting contenders. The way I'm wired, and the fact that you have an Apex, I would suggest diy LEDs. Dimmable T5s would be pretty sexy too. Maybe diy LEDs and an T5 supplement?
 
Well I dove in deep and bought hydras from AI today with independent rail mounts and the controller! Only bought one fixture as of now since I have at least 30 days before corals and one should get the rock going.. My Marco rock showed up today 25 lbs of shelf and 50 lbs of regular I have some BRS tonga branch as well as 15 lbs of BRS pukani dry rock... Tank made it upstairs from mockup downstairs and it looks sexxy I also mounted both independent mounting rails to the back with spacing of about 3.75" between the hydras to really light the center and eliminate spillage out the sides < are they to close?> looking for input before I get it set in stone they are almost perfecly centered as well from front to back... They are setback about 1.5 inches off center towards rear of tank. They should look super sleek with no wires ect on nice aluminum extruded bars
 
I found my new favorite couch seat lol thanks guys hope I made a good choice on lights did you read my spacing setup reef logic what do you think also should I have water tested everything downstairs? I was thinking of just filling the lines and overflow to leak test upstairs without wasting water downstairs filling it ect plus I didn't wanna final glue to my bulkheads in the garage.. Couldn't move the tank then
 
Hey Glenn, I'm not real familiar with the Hydra, might want to Google some set-ups of folks who use them, I'd hate to steer you wrong! Also, I'd be nervous as hell water testing on those sexy wood floors lol, but if you are confident with your plumbing skills, shouldn't be a problem! I ran mine with fresh water for several days to stress test it and found that I had small drip leaks in my Herbie overflow that had to be corrected. They were minor, but I knew they would lead to salt creep, so I fixed them ;) They were just pressure drips where I didn't have the unions and what not glued.

Hell just fill'er up, let's get this party started.
 
Thanks guys and I glued everything good. So I'm confident guess ill let her rip! Thanks for the kind words and kratos the colony is doing awesome in my cube all opened and pretty! I have that green sps or whatever it is by the sunnyd's right under the light hope it grows or lives for now
 
I don't know which I like more, now. The tank and stand, or the room it's in! Any idea for a fill date?
 
soo late last night I plugged in the hydra and held it centered over the tank and I think one unit will do the job.... it spills a lot of light out of the sides... at 100% or am I foolish and should be using two
 
Again, not familiar with your unit, but most of those fixtures are recommended for a 2' x 2' coverage area. and unless you plan on having SPS growing up your glass you wont need 100% par on the sides. I have a 4' tank and have a 3' heatsink, centered. I'm only using 65% intensity currently because I was at 80% and baked a few corals.... LED's are very strong, more so than they appear. You will "think" they need to be cranked up, but your corals will say WTF dude....
 
Here's a par graph. This is measured in air. Penetrating water will reduce the par even more. I think you need at least two if not more.

good info sparky I think I willleave the two up and just dial them down... they are only 3" apart and centered in the tank so im guessing they will cover everything pretty well

Click to expand...

Sounds like a good plan. Based on the narrow rectangular shape of them and the larger cube shape of your tank I woild place them with the long sides parallel to each other and about ten inches apart splitting the cube in thirds. If you het what I mean. Lol.

yes I sort of get it ill increase the spacing between them tonight... bump it to about 6" or so which will be about 9" from center of led cluster to center of led cluster im at about 5.5" center to center right now
 
Yes keep them close enough together so there's no shadowing in the center yet far enough apart to get good coverage and par near the sides.
