My pool has undergone a number of weeks of recent stain removal. Chemistry is almost balanced and crystal clear water. Stains had progressively got worse over months.
Not sure if this was Covid impact, rubbish salt, watered down chemicals, Green coloured acid to name a few.
In summary removed most stains, but this step still has areas of staining. Yellowish/brown in the corners, on the step. Also bottom of the pool is a patch.
Attached photos appreciate some thoughts- as mentioned have been cleaning, brushing and testing regularly. Just not always updating my poolmath sorry.
But I do test more recently FC at 5 now, PH 7.4 becoming steady. Using chlorine and acid and not my swg (seem to
Create more staining).
