Biofilm?

[DustinRS]

All,
I’m having a heck of a time with the film around the water line in the picture. This is a used tub, was drained with rv antifreeze in it when I picked it up this month. After fist fill, the kids got a rash. I ran a full decontamination (spa purge 24hrs, drain, refill, super chlorinate 1hr, drain, refill) and it’s still there. Also getting some foam, thought at first it was from the leftover purge but not so sure now. Water is crystal clear. Alkalinity is 200, just put in oh down to reduce hut otherwise chemicals check out.

Help!

Give the tub a cleaning with Ahhsome.

@Newdude has a few pics of the process you might be able to find doing a search (hopefully he'll see this and post them ).

While I used AhhhSome and was nauseated at all the gunk it removed from my tub, I sadly didn't get any pics. I was busy working with wet and I always pitch the phone in those situations, being a klutz who drops phones.

@jseyfert3 has a great writeup here

Preview, filling after first dump and wiping all walls with Ahh-some in a spray bottle. My hair is a bit wet as snow is falling. Supposed to get up to 6 inches tonight and tomorrow. This is a really nice spa. The dirt anf cloudy water was hiding some of that beforehand. I don't have filters in...
