Temp Effect On Blackout

I recently started using EI and have noticed significant results, but I have some remnants of BGA. I decided to nip it in the bud and do a blackout and am currently at the end of day 1.

I live in Arizona and have always had a marginal problem keeping my tank cooled. I typically have it running between 79.5 and 81 degrees and there's not much I can do to control it. The only cooling I get is from normal evaporation. I have tested the difference between a closed top tank and an open top tank at roughly 2 degrees here in the arid southwest.

Now that I have the tank completely covered for the blackout, the temp has risen to 83 degrees. My questions are:

Does the high temp effect the ability of the blackout to work?
Will three days in a covered tank at 83 degrees harm my fish and plants?

If so, I could quickly stop the blackout and go the Maricyn route. All advice is appreciated.

thanks!

Thanks Peter!

I have a fan running already that blows cold AC into the cabinet. If you think 83 degrees is okay, then I'll stick with it. I think I'm doing it right. I did a 60% WC and cleaned as much as I could, dosed my normal EI dose and closed it up. I'll open it on Sunday, my regular WC day, do a deep gravel vac, and reset the tank's EI dose. I'll also change out my cannister filter and I will NEVER allow my nitrates to fall out of range again.
