Ok I have had a hot tub for 5 years now and have never really taken care of the water just add bromine. Started it up and decided to keep everything in check. I have kept PH,Bromine and Alkilinity in perfect as to what the test strips tell me. 2 weeks went by and i've had maby 10 bathers with a few session lasting 3 hours+. My new filter clogged in 2 weeks and are very greasy. i replaced them with new ones and use some non chlorine shock and a bit of algeacide ( not much) and now I have this very greasy yellowish cottage cheese looking stuff all around the rim of water and floating in water. What is this and how do I stop it from ever happingin again?
