Question
Recently finished a slam on the pool, check my sig below for specs.
The water is clear, but if you run your hand under the waterline and over the walls of the pool there is some sort of scaly white substance on the pool walls, it feels rough to the touch and when it flakes off it looks like soap powder flakes.
FC and PH are all within norms, what should I test for? and what is this substance?
Thanks
