Can anyone help. I have an IPool (10ft X 6ft and 5ft deep) in my garage. I keep the chemicals up well. But this black dust accumulates at the bottom. [FONT=&quot] If I stir it up it disappears.

I run the filter but I guess it settles to the bottom and does not go through the filter--or it passes through it. I even sweep the pool and stir it up while running the pump/filter.

Anyone have any suggestions? black dust at bottom.JPG real hard to see, but black dust-like material gathers after hours of pump not running.

I changed to a new filter and swept pool several times while pump/filter ran.

Welcome to TFP!
