I have been out of reef keeping for 15 years, my last tank was a 150 gallon coral tank with a 200 gallon sump in the basement. I really want to get back into keeping sps and softies but I don't even know where to start with the best equipment. I really like the aio 20 gallon looks but what to get with it for pumps, top offs and skimmers, lights and filters? I noticed there are lots of builds but Noone asking what is the best to get to start with and is there a all in one tank that already has everything that is good quality? I learned from my previous tank that going cheap never saved money. Recommendations would be great thanks Jeff
