This has happened to me a few time over the years with different skimmer. Every time it happened either the skimmer needed to be cleaned or some odd was going on with my water. WC and fresh carbon always fixed the second issue.
So my skimmer is back to Normal operation With Help from you and SCA Aquariums Thanks everyone!!!
Just wanted to tell you that I contacted the company who makes my skimmer and explained what was happening and after going back and forth with them through emails (With GREAT CUSTOMER SUPPORT) they sent me a new PumP for the skimmer for FREE!!!! They where Thinking it was the pump. SO I JUST WANTED TO SPREAD THE WORD ON A COMPANY THAT STANDS BEHIND THEIR CUSTOMERS. (SCA - Aquariums)( Model #SCA-100 )
