Wondering if anyone can explain why the return chamber of the sump is the only chamber affected by evaporation. This is where the ATO level probe goes and where top off water is added. I have a Red Sea tank with a separate return chamber from the rest of the sump.
I'm getting ready to do my initial fill and I can't quite figure this out. Thanks.
