Speakling of heat, I turned off my $6 fan from Walmart two nights ago. The tank was at 77F,
and it seemed rediculous to keep the fan running all night. Surely the heater would have to
kick on to avoid any further chilling.

I keep my house at 75F, and we've been breaking 100F lately. (ugh!) Anyway, I was working
all day Friday and forgot all about that fan. Look at the tank and it was at 86F!!!! The
only reason I noticed was because when I lifted the canopy, a ton of heat poured out. (330w
VHO). Turned the fan back on, and this morning I was back at 77F again.

The amazing thing to me is that everything in the tank looked fine even after the sauna
treatment.

I'm not going to mess with the fan again. grin

I would like to know more about your setup before giving advice, it seems your setup is
holding in more heat than it should be, or something else is broken

at 112gallons and only 2 175w MH lights I suspect a 3" fan could take care of that heat
over that much water. while my tank is no longer setup that way, I did have a 37T ran with
more lighting than you have posted for your 110, including the 2 175w MH bulbs, some PC
over the tank, the incandescent over the refugium lots of pumps and such. and used a TEC
based chiller and a fan to keep it cool

i live in SoCal so the summers here also reach the 90's easily
