So I bought two tao dimmable led
panels and retrofit them into a new hood to replace my quad t5 HO
fixture. I did the switch about 2 weeks ago and the lights are about 8 inches from the surface of the water and the tank is 21" deep (75 G). I started with the lights dimmed all the way down and it pretty much matches the intesity of the T5s. At least it looks like it matches the intensity I'm sure its more intense on a PAR basis.
My question is for anyone that has gone from the 4 x 54W t5s to LEDs- how long should I wait to start turning them up, and then as I do by how much?
I ask because a couple days ago I added a birdsnest frag that I picked up and put it on a frag rack about 6" from the SB and decided to turn the dimmer slightly to increase the light, maybe 1 of the dots on the knob. The next day a galaxea rock on the SB was fried... but nothing else in the tank looked bad- not even mushrooms or zoas that are higher than the galaxea. I plan to do a different thread on the coral because I suspect this may be something else. This thread is more for sharing experiences for people upgrading or switching lights and proper acclimation procedures.
The colors this thing produces are rediculous by the way- even turned all the way down the tank looks way better than the t5s.
