We have a 15,000 gallon pool and jacuzzi. When I was cleaning the jacuzzi with a wire brush I noticed groups of dark black or dark blue little rocks that are connected to the plaster. They can not be scrubbed off with the wire brush but I can pick them off with my fingernail. They look like little flat rocks, I mean real little. Has anyone experieced this before? The jacuzzi has not been hot since last summer. Its a salt water system and while Im at it we also have green algae that grows in the corners. Any help would be amazing!!!
Thanks,
NAtalie
