We recently had a bad wildfire (welcome to California) and then mud slides. The first slide was all of the organic ash from the fire. This "mud" made it to the pool. There was about eight inches of mud at the bottom.
We drained the pool and did an acid wash. When we refilled the pool we noticed yellow/brown stains arond the sides of the pool at the bottom where the mud was. we tried a chlorine treatment, but it's still there.
The stains appear to be growing, but it is hard to tell as the stains are visable when the sun shines, but almost disappear when a cloud blocks the sun. Now the stains appear on the walls of the pool (lighter than the stains at the bottom).
My pool tech thinks I need to replaster, but I am thinking it is Mustard Algae and should be treated.
Any thoughts?
