Hello, new to the pool thing. Question. I just opened my 16x32 salt water inground pool with a cartridge filter system, 3 years old. The water was crystal clear with a lot of dirt on the bottom. Did not add any chemicals to it at that time. So I decided to vacuum the dirt and everthing was great and spotless. I then noticed that there was dirt being shot back through the return lines. And now, the pool is dirty again and is a little cloudy. I checked all piping and cleaned the skimmer basket as well as the pump basket which was very full of worms and dirt. I even cleaned the cartridge filters too. Should I shock the pool? And let it take its course?
