I am wondering if it's possible to have too much air moving across my MH fixtures as to prevent them from getting up to temperature and/or PAR value. I'm running ROIII's with Reeflux DE 10k's on IceCap 250 eballasts. Recently I've been noticing some STN on some of my SPS and one of my oldest LPS's (
trumpet coral). Adding a blower type fan is 1 of the things I've changed lately in the last month or so. It's on a
Ranco temp controller so it only comes on when the tank temp reaches 77 +1 degrees. The only other thing I've changed is to remove 2 of my Actinic+ T5 bulbs out of the array of lights. This leaves me with 2 true actinic and the 2 x 250 10k bulbs already mentioned. Almost forgot, around the same timeframe, I also changed the temp control to come on at 78 instead of 80, thereby reducing my temperature and of course increasing my evaporation. Any ideas?
Today I moved the blower fan to circulate air in the sump area and also put the actinic + bulbs back on.
