View Full Version : Coralife T5 HO 24" Fixture

I have this over my 20l set up and I bought one replacement t5 bulb (14w 10,000k "daylight") for it to increase light for corals. Now that I look at it, I really thought it was actinic but I guess it is not :hmm1:

The stock bulbs that came with it are Coralife 6700k bulbs, of which I have one in the fixture over my tank.

Should I replace this bulb (6700k) with another 10,000k 14w bulb or get an actinic one?

get the actinic so you'll have one 10k one blue

Thanks! They have one actinic at the closest LFS to me, so I will be trying to get that soon.

Ok, I got the actinic...WOW so much blue, but my lighting is so much dimmer now, corals look great though.

Should I be worried that the brightness isn't nearly what is used to be?
