I currently have two skimmers available to use on the tank in the library. The volume of the RedSea 750 XXL according to RedSea is 200 gallons total volume. I have a ASM G-3 and a Bubble Magus Curve 7. According to the manufacturer the Curve 7 is rated from 185-240 gallons. Both skimmers are in fine working order and the only thing on the ASM that is original is the body and it pulls tons of gunk out of the tank already. I am leaning toward the if it ain't broke don't fix it method of thinking, but the Curve 7 is a nice little skimmer. What do you guys think? Drop the ASM or keep it?
