looking for some help. . Cant figure out what this stain is or what to do to fix it. Its all over pool. mfg of course says its calcium staining. i hit it with straight acid. No change. It's in the surface. Not on it.
We installed this fiberglass shell three seasons ago. I have all water chem records going back to day one and the pool has always been in LSI balance. The pool is one block from ocean and did sit full of sea water for three months after the hurricane. Any thoughts.
System won't let me load pic. I can email if requested.
