Thereof, how is combined chlorine treated?

Chloramines can be removed from pool water by the following four methods:

1. By adding a high dose of chlorine, liquid or granular chlorine.
2. By adding a non-chlorine shock, aka MPS to the water.
3. By adding ozone to the water.
4. By adding Zeolite sand to a sand filter, to replace regular filter sand.

Also Know, what happens if combined chlorine is high? High combined chlorine. If the combined chlorine is inorganic chloramines, then you can shock the pool with a higher Free Chlorine (FC) level to get rid of it. If it's organic chloramines, they can persist longer. If you can expose the pool to the UV in sunlight, then that can help considerably.

Considering this, is combined chlorine bad?

Combined chlorine is the source of bad “chlorine” smell, red eyes and irritated skin from pool water. So, once you know the level of combined chlorine in your pool, you will have to add about 10 times that amount of free chlorine to get rid of it – this process is otherwise known as overdosing or super-chlorination.

Why is my chlorine level so high?

Adding too much pool shock or putting too many chlorine tablets to the feeder can both result in very high levels of chlorine. A common way to over-chlorinate a pool, is when a liquid chlorine pump is left running all night; coming in the next day to a green-ish looking pool.
