LED light heat

AdamG280 · Jun 22, 2023

Hi everybody,
I started cycling my tank about a week ago and I noticed my freshwater tank stays at about 77 degrees and it has an LED strip in there. Of course, I haven’t turned on the reef tank LEDs, but it’s reading between 79 and 80. I’m afraid they will overheat the tank. There won’t be heat actually getting through from the lamp, though, because I have a glass lid. I’m wondering if it won’t create some kind of greenhouse effect. Any advice?

You're right about a glass lid will helping a system retain heat, whether it's from lights or from pumps and other equipment. First thing I would try is adding a fan to the stand to ventilate it. Evaporative cooling is going to be the cheapest and easiest way to cool your tank so consider two fans one venting the stand and one blowing on the surface water in the sump/refugium.

Thanks. I thought so. The heat in here is super dry and hot here with the baseboard heating in the winter and hard to manage since all the rooms are different temperatures. I’ve decided to get a chiller/heater to cover my bases.
