Kicking around ideas for a 120x36x30 build I'm in the process of putting together. I'd really like to stay away from MH for a few reasons. 1) They don't lay out well (IMHO) in a 3 foot wide tank, plus I'm trying to control heat (and electricity) for this set up.
The tank is going to be a mixed sps/lps/softies tank. I was planning on an icecap 660 slr setup on a custom rack. There would be 3 pairs of 60's driving 3 60" bulbs. So that makes 18 bulbs (9 for each 5 feet) for a total of 1440 watts (1800 overdriven) as far as I can tell.
I was going to space the bulbs so that I can turn them on 3 at a time staggered to simulate sunrise and sunset.
My questions are the following:
1) Is this enough light? I know it sounds stupid as its damn near 2 kilowatts but it IS a big tank.
2) Is this too much light? Again, Its not going to be a SPS dominated tank, but I want the option to keep sps. I'm looking for a well balanced good looking tank as sps is part of the picture, but not the whole picture.
3) I see smaller tanks with 8 bulb setups. On the above setup am I going to have to keep SPS at the top, bottom, in the middle? If I can't keep SPS on the bottom of a 30" tank its no biggie... Its going to be a ssb/dsb anyways so more realistically 26 inches.. but still.
4) How do I mount the cooling fans for the bulbs? Do I mount them on each end of the rack with one set pushing and one pulling? Do I enclose the rack (seems wrong?) Do I have them blow width (3 foot) way?
Thanks much for you time!
