So I have tried everything my pool place has told me. I took my water to them and they say the water is balance with the chemicals and such. Said my chlorine level was good my phone and alkalinity were good and every thing else. I have tried Metal Free and that did not help. I have tried a copper based algecide that the pool place gave me and the water still has the yellow tent. I just don't know what to do. I have used a couple of different shocks but most from the pool place not sure the brand. Help don't know what to do. I just want normal water. It is clear just a little yellow.
