When you put in the clarifier, are you turning off the pump at all? In the past I have used a "flocculant" and after letting it circulate for about 2 hours, I shut the filter off until the water is clear (this can be up to 48 hours) and there is a bunch of "stuff" on the bottom. Then I vacuum to waste and the water is clear. If the chlorine is holding, and the water is cloudy, you may just have to let the "stuff" sink to the bottom, and then vacuum to waste so it is out of the pool for good. Just my 2 cents, cause I know how frustrating it could be!
