We had our pool resurfaced in November. The company also added StartupTec during the refill and I purchased the ten day service option where they sent people to brush down the pool and treat as needed to ensure that the surface cured correctly. Four months later, my pool walls look like they are dripping. I've contacted the company and am awaiting their response, but in the meantime I thought I would get opinions from this pool of knowledge (pun totally intended!). Anyone have any idea what can cause this? It is all around the pool, mostly toward the top. The pictures arent great, but I don't have an underwater camera. You'll get the idea.
