What is the harm of running with high CYA?? Is it harmful or just expensive? THANKS (can't really drain pool now)
High CYA...........

how high are we talking about? Up to a certain point it can be managed but it does complicate pool maintenance.
The primary issue is that you need to maintain the correct FC level for your CYA level. As the CYA continues to go up various other issues come into play, such as high FC levels interfering with PH readings, the huge amounts of chlorine needed to fight algae, and significant difficulties measuring just how high the CYA level really is when it is above 100.
Certain products used for shocking your pool, like dichlor, do contain CYA and would therefore increase the CYA level.
The reason we recommend bleach/liquid chlorine for shocking your pool is because it does not have negative side effects, like raising the CYA.

How's about some pics or test results. Alot of questions here, can you give us some more specifics about what you are dealing with, perhaps we can help better that way.
