My lights ramp up from 10 until 11:30. They stay at their max peak until 6:30, and then ramp down until 8:00. I had originally had the ramp up and down be 2hrs with the same total 10 hr photo period. This was on an old tank that had terrible algae problems. I’ve since upgraded to a new tank and PAR matched, but kept the same photo period (with the small ramp adjustment). Everything seems fine. No algae at all that I attribute to proper live rock this time, as well as a bristletooth tang & a ton of trochus snails. Anyway, 10 hrs total seems short to me. Might I get better coral growth/health long term if I move closer to 12 hr photo period? Or, is this a “if it ain’t broke, don’t fix it” scenario?
Thanks.
Thanks.
