I did not like the color of the bulb. It looked a little yellow to me. Switched to the 20k radium bulb and I am much happier. The corals are coloring up bettor also.
Jason, I've been using the Radium bulb with a PFO HQI ballast, which is what Aqualine recommends also. Are you using a std. ballast? Thanks for the reply.
Blue Ring,i didn't know you needed a hqi for the
10k ab bulbs. i have them on a std. ballast
& they look fine to me.. i do have a hqi ballast
next to the 10k's so maybe i'll switch bulbs to
