Chiller Help

[JohnnyBassMan]

Yesterday afternoon I looked at the sump and noticed both heaters showed rapid red light flashing. This means the temp is high, therefore I looked at the temp gauge and it said 85 Degree F. We had the windows open all day and the inside house temp was 79 degree F. If we don’t run the AC unit, still not sure this will help; I will need to lower the tank temp 5 to 7 degree F.
I have total of 115g water and the display tank is 75g. If a chiller is needed, what size do I need?

Try placing a fan blowing on surface of your water. THis helped me out on my 30gal last summer when temps kept rising. I am no expert on chillers but my guess would be either 1/5hp-1/4hp, But that also depends on how much equipment you have running (pumps,lighting,ect)
