I let my pH slide low this year down to 6.8. It's been slowly sliding since I opened 2 months ago. I finally brought the ph back up to 7.2+ and the liner got brown stained, the water got a little cloudy and has a green tint.
Ascorbic acid test takes the stain out.
I added some good metal out and some iron precipitated out on the bottom of the pool.
It's been 24 hours. Water still looks green and slightly cloudy. Stains are lightening a little.
What's my next move?
I could drop the ph and get the copper and iron back into the water then do some water changing.....
