I know this is probably a repost and I apologize profusely for that but I couldn't find a related topic in an existing thread.
I have a dark-bottom pool and since about eight months after we built it, white stains have been appearing throughout. I was told it has to do with not keeping the pH levels right but no matter how diligently I track them, the spots don't seem to fade or change. They are throughout the pool and spa including over the bottom of the pool when the vaccum travels.
I have those colored test strips for dummies and manage the chemical levels as closely as possible.
Any advice anyone has so that I can get the pool's plaster back to its original, pristine condition?
Thanks for your help.
