The tank is 22" deep 4' long 80gal. All sps, 26 different species; acro, monti and pocillopora. Lighting is 10" off of the top and consists of two 250 watt 14k Pheonix hqi metal halides and 4 t5 ho 420 actinics. Actinics are on for ten hours and the halides for 8. This is the same system scheme I've used for 25+ years but this is the first time I've had a controller and can see the temp swings. Temp swings during the winter were from 77 to 80.5/80.7 daily. This tank has been set up for five months with 2"-3" of growth shown in 95% of the coral with zero casualties. Temps are now starting to hit 82-82.5 and I'm getting concerned, no adverse effects shown yet.
I can't afford a chiller right now so my question is what do you think is the best option;
1. Reduce the photoperiod.
2. Raise the lights.
3. Install a fan system that attaches to the top of the tank.
4. Other.......
Not even sure I should be concerned since I've never had an issue in the past. It's just different now since I can see the temp swings on my phone.
