I use dichlor powder. There is some impression from stones which fell in pool over the winter - a few of them. That is not my major problem.
I get a lot of dirt - from air, surrounding. These look like dirt to me. but trapped in something...
I have certain my grayish deposits on my pool floor. They appeared over the month.
Wire brush has not been effective. Super Chlorination has not solved this issue.
Please give me some remediation ideas.
Thank you.
