bottom of pool, black stains

Postby zlm7w » Mon 23 Feb, 2009 23:40

I have a underground pool, finished with marblite. Have black stains showing up at the bottom corners of pool. Anyone with suggestions on how to remove them, what is causing this? I have tried srubbing them but
no luck.

Could you describe the stains a little.

Often stains are a result of metals or tannins in the water, but other times algae can give the impression of staining.
