I am trying to decide whether I need to buy a chiller for my tank. If I do get a chiller, I am going to get a Pacific Coast CL280. I have a 90 gallon acrylic tank and it will have 2-250 Watt HQI 10k's with 2- T5 actinics with 2- 4" fans. I would like to know if fellow reefers with similar setups have heat issues. I know it may be different for my specific tank, but if anyone with the same or similar setup knows how high the temp will go during the heat of the day please let me know. During the hot summers here in Houston, I'll probably keep my air at 69/70. Thanks in advance for any help!
