:swear: i HATE skimmers!!! i just bought a new corallife 65g skimmer for my 55 gal. tank. and i still can't figure it out! the cup on top that is suppose to collect the waste wants to keep filling with water. i have tries to adjust the air and water flow. but it still keeps filling with bubbles that turn into water and fills the cup on top and then it wants to over flow..so i put a drain hose on the attchment on the cup so it would flow into a 5 gal. bucket..and the bucket get's full..it just doesn't want to stop. i also did a 40% water change..and i haven't added any meds. or chemicals to this tank in for months..just do my water changes .. so i have no idea whats wrong with it...except it must be JUNK...any ideas out there of what i might be doing wrong??? the skimmer is brand new and i hooked it up right..i even made the guy from my LFS come and look at it..he can't understand it either..he told me to do the water change and to hook up the hose and let it run..but it still not working right..sorry for such a long question..but any ideas would be greatly appreciated....
