which of these two ballast do you find the best fit when replacing old vho setup with 4 4' HO- T-5 bulbs. And will the ice capp 660 run 4 bulbs or 3 bulbs? chime in and help me figure this out. It will run on A mostly SPS tank.
I switched over from an ARO ballast running two 4' VHO's to an icecap 660 running 4X 4' T5HO's with individual reflectors. The difference is amazing. I have a 2' deep watercolumn, so I decided that the icecap overdriving the T5's would give me the penetration that I wanted lower in the tank. I currently have SPS, LPS, Softies, Shrooms, Ricordias, just about everything you can have. Everything seems happy. I keep my SPS in the top 1/2 of the tank and my green sps and my mili have shown signs of growth in just the past week that I've had them.
I would pony up the extra dough for a 660 to run the 4' T5's at 80w IF you have a tank that is deeper than 18". If not, I would just use the Workhorse ballasts to drive the T5's.
