Lighting for 120

kendo · 09/22/2018, 06:04 PM

Hi, I might be getting a 120 gallon and was wondering if three AI prime HD’s and 4 t-5s mounted in the Aquatic life hybrid would be enough light to grow sps corals.
Thanks

I would say yes. The 4 t-5 bulbs will support about 50% of the lighting needs and the 3 additional fixtures should carry the rest easily. Keep in mind if this has a cross brace the center fixture will be obscured and partially wasted, in that case you may want to think about going to 2 26's instead.

The xr15 has almost double the output of the AI Prime HD, so yes, it would be plenty of light. You really can't go wrong with either setup. The only reason I personally would go with the AI Prime is the cost. I am just not willing to spend twice as much if the Prime's can do the job. Just my $0.02.

So, I have a 120 mixed reef-no SPS-4' long and 24" deep. If I wanted to go AI, would 2 x Hydra 26 be the way to go? Could I get away with 2 x HD Prime? I do have a brace down the middle of the tank.

For a tank with those dimensions, I would definitely go with the 26HD's over the Prime HD's.

Thanks for the reply. From my research, I think 2 x 26HD's will be fine. Am looking at the 52's but think for my purposes, it may be more than I need.
