Thanks for the advice, everyone. I'll dial it back to 83°F and monitor. Heater's a Fluval E300, and I've got a backup thermometer coming tomorrow.

My discus tank is sitting at 86°F, but they seem stressed. Water params are good, 0 ammonia, 0 nitrite, 10 nitrate. Tank is 75 gallons, planted with driftwood, and I do 30% water changes twice a week. Should I lower the temp?
