We're having some odd weather where I live, one day it will be rather warm followed by the next week of cool weather. Today the high hit right around 75F, and the room where my tank is at heat up and I came home to an 82F tank with 3 dead fish. Obviously I didn't have the oxygen for that high of temps. I have both my canisters pointed at the surface but just so it agitates but doesn't break. I have spent my evening doing small water changes to gradually bring that temp down to where it normally is at 78F.

The rest of the week is in the 50s and the place where I live now I have to use window AC units and the place is just horrible for insulation so my electric bill in the summer for a 500 square feet 1 bedroom is $300+. So I do try to go as long as possible without having to put those puppies in. Moving to a new place in July that is MUCH better for insulation and I won't have to worry about this.

Anyways...I think for a safety measure I'd like to drop the water level in my tank, so came here to ask what would be a good level below the trim to insure this doesn't happen again and so my canister filters don't bite the dust? I feel if I do this throughout the rest of April and into May it can be sort of like an insurance policy if we get one hot day out of ten.

Granted, an inch below the trim makes it so one canister breaks the surface and provides a ton of water movement. I guess I also came here to post how much this sucks as I lost two huge fat yoyo loaches and a beautiful Salvini female.
 
If 4 degrees caused your fish to die then you have serious oxygenation issues already. If you run nothing but canister filters with no other kind of surface agitation then what you need to do is set the water level where you want it and then set the return nozzles of your canister filters so they are sucking air off the surface of the water which will oxygenate your water very well. Its a little noisy but its the best way. All filter nozzles are made to be placed in the water column wherever you need it. The canister is not hurt by this, they are meant to be used in such a way. Only if your sucking air into the canister through your intake can it hurt it.

Yea my tanks are at 82 all the time when it hot and dose not affect the fish at all. Really that's the temp you want it at to breed cichlids

Nope, dropped the temp back down, water level is about 2 inches lower then the trim and all are fine.

Keep in mind it was 82F at 7pm CST, I have no idea how hot it got during the afternoon.
 
I don't "keep" it down it naturally drops. I'll leave for school at 7 and come back at 4 and be missing an inch to two inches of water in all the tanks! It's crazy! This is just from my window opened with one of those dual fans in it but not on. It's so crazy!
