Looks nice, I have one of these.
With the lid down in the summer, you will have trouble with high water temperature, unless you keep the house a/c low.
The small fan add on did little to help mine.
I ended up with a 1/10hp chiller in cabinet.
I like the system...........use mine as a pseudo-quarrantine tank for my other systems.
If you by addons cabinet fan (chiller), replacement lights, pumps, surface skimmer upgrade, etc. buy direct from Red Sea in Houston, cheaper than marine depot.
