Reviving this post.


Ive been playing a little with my lights lately, Adjusting a little here/there. I like seeing my fish, but having a battle with Cyano. One thing I just noticed tonight, the fish seem to not like the Midday bulbs.?! When they go out, then the fish seem more active. My light is about 6" above the water. It's a T5 4 bulb 24" TEK light. maybe a higher K rating?? WHat K rating before the bulbs noticably shift to blue? I have Geismann Actinic +(22000K) and Midday's (6000K)
