Do I need a chiller?
Hi everyone,
I am thinking of purchasing a 175 watt metal halide for my 50 gallon tank with a 20 gallon sump. The tank has no lid on it, just mesh. I run approximately 350 GPH through the sump and have 2 koralia 750 power heads for flow. I am in the first floor of a house and the tank is never exposed to sunlight. Do you think I will need to run a chiller to have a fixture like this? Thanks for all you input!
