Hi, these are my lighting schedule:-
White light: 16:30 to 23:30
Blue light: 20:00 to 00:30
Yesterday, I have adjusted my chiller temp to 27.5 degrees;
As I found out that it kicks in too often;
This is because my surrounding cause the water temp to increase to 28+ quite fast;
So by adjusting to 27.5 degrees, the chiller kicks in less often.
Though of course I prefer 26.5 degrees;
Nevertheless; I may change my chiller to 1/5 hp one in the near future.
Just for info, the chiller output is back to the same compartment in the sump from where the input is.
And my chiller is inside the cabinet; with a big hole at the back and occasionally, I open the top part of my cabinet to let hot air out.
Also note that my maxspect temp can go up to 49 degrees when both white and blue lights are on.
