I know that I need to upgrade my skimmer mine is too small for my tank and as things begin to grow it will be a problem. Plus I am sick of cleaning every other day. At Reefstock I saw the Hydor and CAD Lights Aquariums skimmers and they both looked pretty good but I would like some opinions or testimonials. I am currently running a 225 g with an old 55 and 30 g as sump and fuge. Any have or seen these in action? I'd really like to not break the bank and am limited on space between the top of my sump and the bottom of my tank so external is also a good option and the Hydor could go either way.
