Ring Around Pool- how do I clean
With all the rain the level of my pool was too high for quite a while. I recently drained it back down to a normal level. Now I have a white ring around the pool. Scrubbing it is not removing it. How do I get rid of it? It is flagstone, salt water system with the major issue being on a backsplash.
I also have similar white coloring around spa and on stone that water flows over into spa. Any tips on how to fix these issues would be much appreciated.
