What Watermom was asking, was what the ingredient in the shock was..not the product name. Hth shock and swim is calcium hypochlorite. When you add a calcium-based product to a pool that already has sky-high calcium, you get milky/cloudy water, regardless of how often you're cleaning the filter--and it's not something that a clarifier is going to help with. You need to lower the calcium level in your water, and stop using cal-hypo for chlorination, otherwise this is going to happen every time you chlorinate the pool. What is the calcium level of your fill water? Also--what did you do to "fix the issue" of low stabilizer?
