Does anyone have any experience with PoolWerx in testing your pool water or making any Polaris repairs? I went in to what I thought was still Dolphin Pools last week and they had different staff and a new system to test water. The young lady stated we needed to broadcast 2 gallon bottles of calcium in our pool. I stated we had never had to do that. She said you usually have to do it on an empty pool and it keeps the gunite from deteriorating. We need to have our Polaris worked on and had always used Dolphin. What company do you use to test water and make small repairs?
