I have the Red Sea Reefer 350 which is about 73 or 74 gallons. I love it.
Well constructed, when tuned the overflow is silent, ultra clear glass, nice silicone job. My one drawback is I wish the cabinet was better ventilated.
I recently bought a CadLight 70g Artisian II tank setup. Theirs is a drilled tank with a sump setup, so not an AIO.
Also not at all pleased with their quality of product either.
