I have a 75 rr with icecap 660 with 4x48 10k bulbs about 4-5 inches from the water...opinions on sps potential (surviability) to thrive with this lighting running a resirc octo not worried about water quality...just the lighting issue or if it is an issue

You shouldn't have a problem growing any montipora...cap or digita ect. I've seen a few acro's grow well under VHO's like Tricolor acro, Vidalia acro, Millies, German blue acro, and sermintosa.

Just make sure to replace your bulbs in a staggard kind of way. Like one every two months. That way they stay strong and you don't have ups and downs in your PAR.

ok sorry not VHO T-5's

 

[jeep9783]

ok would this change anything being that it is t-5s any problems groning acros? Or do i need to add a few more bulbs?

seperate reflectors? overdriven?

 

[jeep9783]

yes overdriven icecap 660 with 4 48in bulbs...forget what the wattage equals something like 53 whats yes individual icecap reflectors...

any other opinions

actinics do very little for growing coral. The 4 T5's should have no problem growing SPS. Idealy 6 over the tank would rock! You can go with a 6500K, 10K, 12K, 14k and two super actinics. GrimReefer on RC has alot of expamles of what t5's to use. Check that out for sure.

 

[blind1993]

this is the rule of thumb i use for sps

55g 4bulb
75g 6bulb
90g 8bulbs

Check out BIGD. He runs t5's on a 180 and has tried many combo's.
