Thanks for your input guys!
I have those magnetic scrapers and I also have a sponge thingie that has a wire rod...the kind you can get at the LFS, or Pet Smart so I can wipe and it will reach down further into the glass. I'll watch to make sure I don't get grit inside the scraper, thanks for bringing that to my attention.
Byron, yes the film is one I can't see from the outside in, but I can feel it is a little slippery on the inside. Don't see any algae yet...so guess that is a good thing. I just didn't want to be taking away any good bacteria and messing up the biological environment of any of my tanks.
