The surface of the water looks like it has pollen/oil/grease/foam on it. What is that? Is it organic/non-organic?
Here is a video of me refilling my CalSpas hot tub with fresh water and immediately the surface of the water looks filthy: https://www.youtube.com/watch?v=Jmme...ature=youtu.be
Here is another video from a few weeks ago: https://www.youtube.com/watch?v=n4t-_TDB1Nk
It's a 2010 CalSpas hot tub located in Finland. I've been using AquaFinesse and chlorine to maintain the water. There was a foam problem from summer 2014 to december and I just kept adding AquaFinesse and chlorine regularly. I tried to fix the problem in december, too late I guess. I followed advice from a spa dealer and what I was able to find on the internet. Among the things I did in december:
- changed the water 2 times
- added sodium bicarbonate
- added Leisure Time's "FoamDown"
- added "JetClean", let it sink in for the night, tried to wash the surfaces with water and vacuumed any remaining water as best as I could. When I refilled the tub I was horrified to see the water was immediately dirty.
Any advice would be greatly appreciated.
