In looking at hot tubs on manufacturers web sites, many of the pictures feature a blue tint to the water. I tend to have a green tint in mine.
Initially, I thought it was algae. Spent $30 on a bottle of Wham-o algaecide. Didn't work. Plus a smart member on this board mentioned that it's very difficult for a tub to grow it becuase of the lack of light.
Second...thought it was lack of sanitizer. I now use Dichlor and keep it at 1-3 ppm w/ ozone. Is that too low ?
Third....thought it could be copper or other minerals in water, so I added slightly more stain and scale last night.
Any thoughts...
P.S. I have had 3 other tubs, and don't remember any of them having a green tint. First two had white shells, the other had a denim blue / marine shell, and now I have the Jacuzzi Premium sahara colour.
Thanks
