I have that system for my 75-gallon. It is only good the way it is for a FOWLR
. If you want a reef tank you need to replace pretty much everything in there..... replace the bio-balls with live rock rubble replace the carbon pillow and glass cylinders with something like chemi-pure or purigen. Otherwise the nitrates stay way too high. I have made those changes and it works pretty good. Except the skimmer kind of sucks, doesnt produce a whole lot of foam. The bottom line is, overall im happy with it, Im not disappointed I bought it, but if I started over again I would get something with a true sump and refugium. It would easily keep a 46gallon FOWLR
in check. I got ripped off when I bought mine from my LFS
(he recommended it) I paid $375 and then a month later I saw it on marinedepot.com and customaquatics.com for about $225 with shipping. I also bought the automatic water top-off attachment for it, which is pretty nice.
