It must be your power heads and lights adding the heat. LED's run cooler and try some more efficient powerheads. maybe clean yours first to see if they're just clogged

I also leave the front and back doors open all the time

i just use the stock power head that comes with the cube. i cube has stock LEDs. Blue is kept open from 5 am to midnight. Pink opens up at 7am to 10 pm. The white is open 12 noon to 7 pm.
i do have another powerhead that comes with my Protein Skimmer.
I suspect its the light but it is just LED.
I will try to open the entire hood just around 4 inches as a temporary solution to see if it works but i dont want to do this daily on a permanent basis.

Also try putting a fan blowing air across the top to dissipate some of the heat

I'd add another small power head aimed at the surface to agitate the water

there's a hydor 240g that agitates water. i also have an air stone placed in the first compartment.
i have a 10k corallife add on but it is outside at the back of the sump (middle compartment). i touched the glass and it is not warm so not really sure if the back light has impact.

In my 29 I found the return pump was heating my tank by 2 degrees. Changed it out for a mj1200

I changed my lighting schedule, which helped with mine some. I'm not home during the day anyway, and keep my home fairly dark even during the day, so not sure the fish/corals care when they get the light. That and keeping the doors open for more evap (REALLY loving the ATO with that)

no its not hit by sunligth. i just lost a head on my frogspawn. i got it with a crack and i know it was struggling. i guess the heat took him out. The other head is still ok.
i just went over 80 again. Shut down the skimmer.
Have a freshwater biocube and it is just 78! This is driving me nuts.

I think it's also important to mention that you're nowhere near the absolute top "temperature threshold". You can run a tank safely up to 84 regularly, 86 I believe is where things start to become problematic.
Part of the reason why people run their tanks on the cooler side is that it's convenient in cooler climates, and also for margin of safety, keeping their tank further away from 86. If you keep your tank at 78 normally, and your AC goes out, you probably have a few dozen hours before you hit 86 on a normal day. If you keep your tank at 83, your margin of error is much closer.
It's also worse to be fluctuating temps than it is to run the tank at a high temperature. If you can consistently keep the tank at 82, it's not a big deal (my tank frequently hits that during the day, and 78-79 at night).
The temps probably didn't kill the frogspawn either. You are right, it was probably struggling. I'd look closer at parameters and how consistent they are (and how you're measuring them). I have to also imagine it likely has to do with tank maturity as well.

I had the same problem
I had the same problem
My biocube 29 would get 82+ easy. i would leave the hood cracked open. Its pretty ghetto but I used the plastic pieces that are in the center of the dog poop bag rolls. I just notched a groove so that it would lock into the frame of the hood. It would hold the hood open about 2.5 inches and helped a lot.
About 1 year ago i picked up a used Aqua Euro chiller off ebay and it has worked great. I think i paid about 150 bucks for it. Also, switched to Steve's LEDs May '16.
