Review on AquaMaxx CO-1 In-Sump Protein Skimmer with Cone Shape by Kelsey Davis

I have just bought a skimmer for the third time. It works great, is one of the quietest skimmers, picks up a lot of waste and adjusts to the water depth. It also has a small footprint for the load it can handle, so it fits perfectly in my limited pallet space. Unfortunately I have one block completely out of order, the other block suddenly started taking in too much air and doesn't draw any foam, only pure water! In short, this is a great skimmer which is why I keep buying it. but after about a year they don't work very well anymore. Maybe I do, but having serviced reef aquariums with several different types and brands of skimmers for about 15 years now, I'd like to believe it's the skimmer and not me.
