Yeah, I think I heard that too about the pulse start. Must be with the re-design of the bulbs because my old Ushios have worked great on M57 ballasts.
I'd like to just swap out a bulb with you but not sure what to get. I believe you carry 4 bulbs in 175w.
10k XM
10k Coralvue
10k Ushio (that's out)
10k (13k) AB
I'm running 250w XM's on a SPS tank, I like them. But this is going on a softie tank of 20" + sandbed so that PAR and increased output might be too much?
Been reading that the new Coralvues are really blue. Not a fan of BLUE bulbs.
Not sure what the AB's are and how they look.
I'm not looking for a BLUE bulb, but something with a little blue would be good. Any suggestions?
