Way back in the 80's ozone and halides were a requirement lol. Halides made heat, tanks needed chiller or were 94 degrees in summer. I'm now in Florida, kept the ozone, using LEDs, although love halide/t5 combo best. My tanks run 78-80 degrees most of year and do well. During heatwaves I lower central air few degrees. Tanks stay 2-3 degrees higher than room temperature.A lot of factors come into play when determining if you'll need a chiller or not for your reef tank. Where you live, the location of your tank, your lighting and more. With it starting to warm up outside I thought it would be a good time to discuss chillers!
What is a chiller?
Here is a simple definition from First Tank Guide: An aquarium chiller is really a small refrigerator which is installed in-line with an external filtration system to cool - or chill - the water as it passes through the system. When coupled with a thermostat, the chiller can prevent the aquarium from rising above a per-determined temperature.
1. Do you run a chiller on your saltwater aquarium?
2. If you answered yes, what brand of chiller are you running?
