what I did was actinics turn on 2 hours then the MH come on for 8-10 hours, then the actinics stay on for 2 hours after that.
problem with trying to guess what is going on over the summer is you need to know what your temps did. 99% of the time summer problems are from temp changes.
I would start logging temps. I bought a themomitor that would record the daily high and low values and I would record them ever morning and see what was going on over a month or so.. this is what based my desision to buy a chiller.. my temp was swinging from 78 to 88 (hotter on real hot days.) after the chiller I had a swing from 79 to 81. which produced much better results in the corals.

Temps have never been a problem as my house is climate controlled. If anything my temp sat at 80 and never really moved day and night, and this also meant my heater never turned on as the pumps, etc did the heating. If anything, now the heater may be used more.
Good advice, I will watch the temps.
