emergency help

Anything lower than the current tank temperature would help to bring down the higher temperature. Depending on what percentage water change you have available, I wouldn't be concerned about slowly or not. 10 - 20% I would change quickly - 50% I would do over a half hour or less.

Good idea to keep some 2l pop bottles frozen with water, just in case. can float them in tank to cool water. Even pop bottles filled with cold tap water will help in emergency. My heater did that once, I caught it at 94F Shrimps and all LPS died. fish and Softies survived though

I would cool it down very slowly! quick temp changes are bad for the tank. Add an extra airstone as was mentioned above. Do not feed the fish either for 1-2 days.

When temp comes to apprx what it should be, do a water change

I would go with the frozen pop bottles in the sump like Dan said. My tank went up to 90 degres last summer during the heat wave since I was not home. Beside my xenia melting everyting made it through. Bring the temp down slowly

86 isnt that bad. Just let it cool down on it's own. It should be ok. Don't shock anything by rapid cooling.

If you already have adequate circulation and oxygenation I dont think that is too warm either. But to avoid future problems you may want to invest in a quality temperature controller.
