I don't think that will help and it will be a lot more expensive than chlorinating liquid or bleach. You need to shock your pool with chlorine and keep adding it until you start registering an FC level. You may have a lot of ammonia in your pool, though normally that comes from a breakdown of CYA by bacteria. Did you just open your pool and find this problem? If so, then that may be what happened, though all the CYA didn't get converted since you still measure some.
