What 250 10k Hqi bulb?

[jsf668]

I have been using Pheonix bulbs for the last few years and have been very disappointed with my coral growth. Which has been pretty much none! I am thinking about going back to an affordable 10k bulb. I have used Ushio in the past but was also looking at the Reeflux 10k bulb. My ballasts are Coralife 250 Hqi. Any suggestions?

I can't believe you don't get coral growth from the Phoenix 250's. I use them on my sps tank and grow is not a problem at all. Check all your parmameters and maybe that's where your problem is at. Also check and make sure calcium levels and alkalinty levels are good including magnesium.
