I have a 14X30 Viking Fiberglass that holds approx. 12.6K gallons.
There are hundreds of "spider-like" hairline cracks in the gel-coat.
The cracks are not in the structure, only in the gel-coat.
Brownish-green stains have settled in the cracks making them visible, appearing like the pool is cracking in hundreds of places. I was told to lower the PH with muriatic acid, and run the filter 24/7. This has not done anything. I have tried to scrub the stains by hand, but it does little to nothing. I am going crazy here with a $30K pool that has unbelivably clean, clear water-that looks like cr*p with all these stains. WaterBear or someone please help !!!!
Thank You in advance.
