The water is clear. My wife thinks it has a green tinge. I'm not so sure it is not some crud on the floor. I will vacuum and see what she thinks. I will put in my new filter, but I must say my old filter looks pretty good. That chlorine really cleaned it. I spray it with a pressure washer and when using softswim, I could spray if for 1/2 an hr and never getting it looking as good as it looks now.
