I have a 3 year old vinyl salt water pool. I have not had any chemistry issues. However, in the past year, I have spent a ton of money trying to get it to stop leaking. One person brought a hydrophone and told me there are hundreds of tiny holes in the bottom. The best I can deduct is that the pool crete was improperly finished. Now there are 1000's of tiny pebbles protruding through the liner floor. I can see where the color has disappeared from the tops of them. My question is regarding guinite. Is it possible to have this liner pulled out and convert the existing pool to guinite?
