I was using Poolife Rapid Shock (Calcium Hypochlorite) and the pool store suggested using Poolife Clean Shock (Sodium DiChhloro-s-Triazinetrione Hydrated) and the pool is now crystal clear. Off course the Clean Shock is about $1.50 more per bag but the clear water is worth it.

So you used a different type of pool shock and it became clear. But I'm wondering if it's just a coincidence and that your CL level was raised high enough to kill the algae. If you put Poolife Rapid Shock instead this last time, your pool could have cleared up also.

Chemically, how would this second type of chlorine help clear up the pool?

The CYA was 34. We never had algae. The hardness was 200. pH was 7.2 and TA was 120. We use an algicide every week. I am going to invest in one of the aforementioned kits. Thanks for all of your responses/suggestions.
