The fiberglass ia blue, the "staining" is a tannish color yet a brighter blue in other spots. The Chemistry is perfect the discoloration is IN the fiberglass.the pool get 80% sun and I understand the fading over time but this is in areas and blotches. I can send a pic but I don't believe I can post on this forum. Again it its SALT chlorinated.

Pool is 1 year old and there are patches of discoloration under the water on the sides and walls. It is not a surface mark as I tried to scrub them. It appears to be in the fiberglass. Thanks for you help!

Installed last Sept removed the Coverlon safety cover had pool service start it up. I noticed "staining " it's in the fiberglass now A perfect leaf imprint for example. Any suggestions to clean it up? Thanks
