I have the Intex SWG model CS7111. My water is clear and clean. pH is 6.8. Alkalinity is 80. Stabilizer is around 30-40. I have to add chlorine at night because the sun eats it up. My stabilizer could be raised a bit, but anyway... However, I have to clean/change my filter every day. The water inside the filter compartment is brown. Also, in the morning, there's little brown dust particles (not algae) settled at the bottom of the pool, which I vacuum out. Any suggestions about how I should handle this? Thanks in advance.
