I don't know if I mentioned it anywhere else in this thread but my tank is old, and the seams are starting to make me nervous. There's at least one chip on one of the corners and the silicone is peeling away or missing in a few spots. I would much rather prevent a leak than clean one up, so I've been thinking about switching to a new tank. And if I'm doing that I might as well upgrade. I thought about it last week and I haven't been able to get the idea out of my head since then so I think it's gonna happen.
Right now the plan is to get a new 120 and drill it myself for a Synergy Reef Ghost overflow. I'm most likely going to use a cinder block and 2x4 stand, and place my sump next to it on a smaller cinder block and 2x4 stand. I'm going to get a new return pump, since I was planning to anyway, and reuse my sump, skimmer, powerheads, rock, sand, and light. I'm probably gonna get a little bit more dry rock.
I'm hoping to have all of this done by the end of the year. I really thought I'd be happy with a 90g when I got it and wasn't planning on upgrading so soon but imo it's just a big risk to take. And once I got the idea in my head for an upgrade I can't get it out.
