I've been using a floater for convience and now find the CYA level of pool as of today was 200. I'm going to be forced to drain some water out and refill. I'll be using bleach or liquid chlorine and hoping not to have to do this again. My question concerns the TFP method and how you carry it out if you go away for an extended period of time or even a few weeks. Do you throw a floater in just for that period and then go back to the TFP method when you return?
