Questions - Need some input

I customized the white balance on a new white frag disk and I was AMAZED by that I saw! I never thought my camera was capable of this sorta stuff. enjoy

After doing a few "best guess" calculations, it appears the snapper hybrid would flow somewhere around 1500 - 1600 gph with the snapper impeller and the calc'd head loss. The pump actually comes with two impellers which can be changed out. My "best guess" calculations suggest, with head losses, the dart would flow around 2200 - 2400 gph. That's around 30x turnover for the tank. But with the dart impeller and at the calc'd head loss, the pump would pull around 180 watts. I'd ...

In September 2008 I finally talked my wife into letting me set up a saltwater tank. We visited several fish stores and asked lots of questions and settled on a 29 gallon complete set up being sold on commission by a fish store near an army base for a soldier going over to the big sand box.

So to make a long story short I have a Odyssea POS 250W MH fixture (with four 65W PC's) that I can no longer get MH bulbs for unless I replace the ballasts. In doing some hunting around online I found that the Icecap 250W ballasts would work. But I have not been able to find anyone with them in stock. I just now read that icecap went out of business. Is that true? Anyone have any ideas on other ballasts that I could use?

I was so close last night to pulling the trigger on two DIY ...
