I have a pool that has scaling along the waterline. I just refilled 66% of the water last week as it had CYA at 90+ and CH was at 410. I have shocked at mustard level already using liquid chlorine and I think the water is balanced, but with TA at 130. Will lowering the TA to 70 help remove the scaling? Or should I just leave the water with measurements below.
FC=6 CYA=25 pH=7.6 TA=130 CH=210
I have 3 trichlor pucks in the water to raise the CYA to 30. Although they don't seem to be dissolving much after 3 days. In the past, a puck usually dissolves in a week.
Although the water is clear, there's blue-green spots all over the walls and floor. I think it's blue algae which I'm hoping will disappear after 4-6 weeks in this BBB method. I have previously posted about this problem but had high CYA at the time.
