I will take the next few days to expand on my previous chemical post. We will start off by looking at chlorine in a little more detail.
To begin, there are two chlorine tests. The really important one is free chlorine. This is the chlorine that oxidizes contaminates from the water. We want the level of free chlorine to be 1 – 3. The second test we can conduct is for combined chlorine. Combined chlorine is a bad form of chlorine and we need to eliminate it. Combined chlorine is responsible for chlorine odors, so if you smell the chlorine in your pool, you most likely have a high combined chlorine reading. To remove this bad chlorine from the water we shock the pool with a granular chlorine. The higher the combined chlorine level gets, the more shock is needed to eliminate it.

Check back soon for clarification of shock types.
