We may at some point in the future drain my neighbours pool.
There are many plaster delaminated spots where black algae is growing. They cannot at the present time afford a replaster job.
I am aware of the in-pool treatment with pucks but there are a lot of areas and I do not think it reaches well under the delaminated areas.
What might be the best method to remove these black algae areas once drained?
In the past I used chlorine soaked rags overnight and scrubbed with a wire brush, it seemed to work but the algae did come back. The return may have been due to them not keeping the pool in proper balance. Is this the best method or could someone know of a better solution?
Thank you.
