Getting back into this super addictive hobby after a 15ish year hiatus. Interesting to see all the changes. Currently setting up a Frankensystem. 12 gal long I just drilled with two 5.2 gal top refugiums (also drilled ) and an acrylic mantis tank (7ish gal) and a sump underneath. All Gonna be connected. What have I started?? I’ll post some pics soon.
