K, I have the 24 aquapod
HQI, 12 gallon JBJ, 24 gallon JBJ with mods and the 28 gallon JBJ with
HQIs.
They are all chiller canidates
IMO. I have to open up the feeding lid during ceratin times of the summer and then I have to raise the entire lid and turn off the lamps on some days. But if you have the 28g
HQI JBJ I assume your corals are light hungry and you can't raise the lid up.... and then you will have a problem without a chiller. You can't get away with the lid down and the lights on throughout the summer without getting a chiller.
