Have a 18k gallon in ground pool with colored plaster (grey).
Upon completion and filling it up, my wife and I noticed rather quickly that we had “streaks” on many of the spa/pool steps. Our pool builder was quite evasive it says such streaks are unavoidable during the gunnite process.
When I first starting maintaining the pool, I used chlorine granules/shock (placed in deep end) that seemed to settle at the bottom of the pool and cause lightening of the plaster in the affected areas.
Recently, I began noticing some “white spots”, which I’m assuming are examples if scaling (TA was found to be 140 after not testing for a couple of winter months).
HELP...are these different types of spots/stains/streaks unavoidable when you have a colored plaster? Is draining and treating with acid the only fix?
