I started this aquarium as a 30g breeder tank. it then turned into a 55g, bc you know bigger is better...lol. I then was gifted the largest tank ive ever owned which is 84 inch 275 gal DT. i upgraded the sump to a 100 gal diy with a fuge. i just recently added the 30gal frag tank to the system with my mangrove in it. just started getting into coral. stand dont match yet...lol
