I previously brought a 56g rimless tank. Have always loves reef tanks but never got involved with them so this is the first go-round. My dad had a 185g custom made tank but that was just coral and that's about it. I heard about this website so figured i would join for some additional information. Always open to hearing about new things! Tank had built in set up for sump and filtration. Just put about 28lbs of live rock in about a week ago with some tester fish. Looking to grab more stuff in a few days if everything is perfect. Hopefully post pictures soon.
