No, I’m in the Midwest, and the tank is in the basement. I had the temp turned up to 83 early on. I had Dino’s and read temp increase may help. It worked for me, but then turned it down. From then it hasn’t dropped below. Only one ai prime, so not anywhere close to producing a lot of heat from the light. My nem tank doesn’t get above 79. So I definitely think it’s the heater.you don't think you need a chiller ?
