Just about 5 years now. I started with a 20 gallon from petco that I frankenstined a sump on the side of then a skimmer. Moved to a waterbox cube and now moved to a reefer 625xxl that's on month 7 and doing well after the usual issues of learning the tank. (aka that stupid redsea overflow valve, replace that thing)
I am liking some of the red sea stuff, the reefmat is nice for sure. The 160s are nice, but I think overkill, I have them at 40% and that seems plenty for lps.
