I have tried everything to get this film off my surface. I have pretty good surface aggitation and I can't get rid of this film. No I dont have a overflow to a sump. My Landlord won't have a added tank since I'm on the second floor. What can I do?
I am just curious, do you ever use like a tubberware bowl for anything like scooping out water or anything at all?
I ask this because we don't have a dishwasher.. we are old school, and we wash everything with down dish soap. Well sometimes when your in a hurry, you use to much soap and don't rinse it well. The bowl get a slimy like feel to it but you cant tell when its dry.
The other day I was scooping out some water for WC and used one of these bowls. As soon as I dipped the bowl in my tank an "oily" film started excreting into the water. like yorkieUK said, I took some higher end paper towels and layered them across the surface. We use to do this for tank installs when something accidently gets into the water or grease gets on the glass and is not cleaned off before its filled.
So in short soap on tubberware + warm water = equals a oily like film.
ALSO, if you was your hands before reaching into the water and you use dish soap, make sure you rinse your hands really well with warm water not cold. I have done this before were I washed my hands with dish soap and cold water really quick and careless. and it did the same thing. Sometimes its not even noticeable at first. I wash my hand every time I touch my tank cause im a smoker. Even if I haven't smoked since I wash them cause I know that everything I touch like, pc mouse, keyboard, drinks, especially cell phone has that tar on them from me touching them. Always make sure im scrubbing between my fingers and in the webs and rinsing really well.
Ill stop rambling on now.
