I’ve had my 36 gal bow front tank for about 9 months now. The filtration is a hang on back filter. I recently picked up a 75 gal tank. My plan is to build a new stand to accommodate the sump and plumbing (and match the decor of the room). I am going to get a 40 gal breeder tank for my sump. My main goal of the tank is to have beautiful colorful fish and corals. I have been reading and researching what to put in the sump but can’t decide if I should use a skimmer. What are the major advantages and disadvantages for a skimmer. I really don’t want to use filter socks. I am going to use a Theiling roller mat instead. I will install 2 heaters. I really am unsure what else should be in the sump. What equipment has been tested and used and you wouldn’t want to live without??
