BiBi Posted February 16, 2011 Report Share Posted February 16, 2011 We installed a 100 % Salt water pool in Texas 1 and 1/2 years ago and about 6 months later, we began to see circular discoloring spots (sort of a gray color) popping up on the plaster below the water line. They grow in diameter and we now have about 1/2 a dozen or so. In addition, we are having a gray line form under the water line all around the pool. Gunite people say it's not their fault, plaster people say it's not their fault. I am assuming there is a chemical composition problem between the gunite and plaster, but I don't know enough about the reactive ingredients to figure this out. Finish is Wet Edge Blue Altima Pebble Plaster Steel / Gunite Also - I have been posting about this and people keep writing about Mottling - what is that? Please help, we want to love our pool and we need our warranty to kick in with one vendor or the other, but at this point, no one knows how to fix it.....

PoolGuyNJ Posted February 17, 2011 Report Share Posted February 17, 2011 Can you either post or put a link to a hi res pic? Current chem levels would help too. Scott Quote Link to comment Share on other sites More sharing options...

Scott Sure - hate to be an idiot, but how do I post the photos to this forum? They are just jpegs Well - I can't figure out how to attach or upload photos to the forum, but try my gallery link. There are three shots on there. You can see graying around tile and the the discoloring spots. http://gallery.me.com/bethanyribbing#100179 Quote Link to comment Share on other sites More sharing options...
PoolGuyNJ Posted February 27, 2011 Report Share Posted February 27, 2011 I looked at the pix. This doesn't appear to a failure of the plaster. It appears to be calcium scale. It's cause by improper pool chemistry, specifically, letting the pH stay too high for an extended period of time. What are you using to test your water?
