Yes it's 8x80w
If I remember correctly
2x ATI Actinic
3x ATI Blue+
3x ATI Coral+
Are you dimming your T5s on your tank? I find it that on my frag tank that is also 12" tall like yours, 6 bulb configuration about 12" above the water is too much. Some corals become really pale, as if they were blasted by too much light, yet PAR meter shows 250-300 par on the sand bed which is about what corals in the main tank get. Of course it could be some chemistry issues as well I guess as the tank is kind of new. Nothing is dying and in fact PE looks good, just that colors are not quite the same as in the main tank![]()
Yes I'm dimming them and only at 60% max right now. I also need to raise the fixture because it's definitely too much light. At 100%, bottom is at 300par. I want to bring that down to 150 at the bottom and around 500-600 on top.
Are you also running LEDs? You should think about adding reefbrite LEDs!!
With an 8 bulb fixture, I would probably do 3 blue plus, 2 actinic, 2 coral plus, and 1 purple plus. And two reefbrites!!!
