Recently started working on this pool which had been neglected in the past. The water wasn’t green but it’s clear the walls and floor hadn’t been brushed or vacuumed in quite some time. There was some evidence of green/yellow looking algae in the skimmer area. Overall the pool wasn’t horrible except for the stains.
I started slamming it at mustard algae strength, cleaning filter, brushing with 50/50 brush 3 days ago. Chlorine is still dropping slightly over night so I’m continuing but seems to be on very tail end. Here is what is remaining in the pictures. In person it’s brown. Copper test came back fine and vitamin c test negative. I plan to use stain test kit if chlorine doesn’t take care of it.
These are pictures after 3 days. It should be noted that the stains exist only where the sun does not shine on the pool this time of year (which makes me thing more algae stain than metal?). Pool is about 17 years old.
What are your thoughts?
