I've been using the TFP method for about a month+ and so far so good. I've been testing and adding my bleach at just about the same time every morning. We are currently in a heat wave and my pool has direct sun all day. I'm thinking about the rest of the summer as I seem to loose about 2-2.5ppm of FC everyday. I'm wondering if it would be better to test and add chemicals later in the day? My pump goes off at 6pm so my question is, if I test and add around 430-5pm is the hour or so enough to circulate the bleach and would it be ok sitting without the pump running from 6pm to 8:30am? Thanks in advance.
