The chlorine level is another problem, so far I've put several pounds of extra strenght shock in and the Chlorine still shows as nonexistant when you test the water.
Ryan,

I watched this thread get side tracked into filter questions when your issue is almost surely chlorine. You must continually put shock levels of chlorine in your pool to get it clear.

If your chlorine diappears, it's because you are killing algae in your pool. The answer is simple....you need more chlorine.
