After joining this great forum a week or so ago I'm beginning to find that all of the advice I've been given on my pool in the past by various folks is full of ****...So, i bring another question that maybe someone here can help answer. Can anyone tell me if the stains on the bottom of my pool are "Algae" (some kind or another), or are they "metal" staining absorbed by the poorly mixed plaster as what I was previously told. (and that a re-plaster would be the answer to fix that)
I'm in the process of currently lowering my CYA (working on a partial or full drain), so I can properly sanitize with lower FC and wanted to know if i should be looking at re-plastering, or just looking at doing a SLAM to get rid of this. (if it's algae)

Thanks in advance for reading!
