I live in Phoenix, AZ. We bought my house 4 months ago, new pool owner. I have been taking care of my pool myself. My chemistry is spot on. I have the Taylor test kit. I rarely use tablets, just keep adding liquid chlorine daily. i keep my FC above 4 most days and my pH is right round 7.6. My CYA is between 50 and 60 most weeks. My problem is a steady dirt residue at the bottom and my pool has turned a grreenish tint. Its frustrating. I manually clean it and I have THE POOL CLEANER, but there's still dirt and a greenish tint(or so I think)) over the past 4 months, it wasnt always that way. I have been very diligent in the pool chemistry. I know what I am doing there but the color is annoyiing. It doesn't look right TO ME.
