Finally fired up my MH that I got from Lostmind (thanks!). Its a custom sealife, dual 175 ballast. Right now I'll just be using one to fire only one bulb on my 38g.
I picked up a bulb socket from Jack at OA (thanks again!), and wired things up at home, to check to make sure that the ballast/bulb is all working. Perfectly fine! Only problem I came across was the ballast. It is very loud. Any reason why? Sounds like a buzzing/hum noise.
