SO........if you've been following along in this thread you already know that one of my NEW Coralve 400w dimmable ballast did not work. I talked directly to David who is the predident and he told me he would not send out a new one until the recieve my old one. He said they have gotten ripped off in the past so this is how they do it. Fine....ok....I can understand that. So anyway the finally got it and after a week and a half (TODAY) Fedex shows up at my door with the new one. I'm thinking, finally i can get the right side of the tank lit. I open the box to find a 250w not dimmable ballast. So I called David and had to leave a message and he returned my call within 20 min. He apologized and told me to keep the 250w ballast. He told me they won't have anymore 400w dimmables for another week or two but as soon as they get the next ones made he will ship it out. I really can't complain to much, they've had great customer service. He also told me that if I didn't have a 250w bulb the 250w ballast would fire my 400w bulb. I don't think I'm going to try it though. Anyway, as soon as this weather clears up I can get this canopy trim finished and start on my stand. More to follow.................
