I would keep an eye out for a Euro reef 80 or 135, or a vertex. BK if you have the $$$

the tank will be 65 Gal, with a 20 or 30 gal sump. accounting for rock space and all i figure the total water volume will be in a 70 Gal range? maybe? i would like an ''ïn sump'' skimmer. that number represent the number of gal. its designed for?
