We just moved to a home with a NON-SWG cartrige filter pool. For the first month we continued to use the pool service that had maintained the pool for the previous owner. I have decided to take on the pool myself and go with the BBB method. I have a few basic questions. We live in FL, the pool gets a reasonable amount of direct sun. There is a fountain overflow from the spa to the pool which runs while the filter is on approximately 5.5 hours per day. The pool service has been shocki9ng the pool every thursday since he said we use it often. During our last week of service i was testing it on a daily basis to get an idea of what it was doing over a weeks time. The FC would be about 6 on the Taylor kit with an CC of 0 with little drop in the fc level. It is now friday a week after the pool service last visit (and shock) and the FC is about 5 and CC 0. I checked the CYA level for the first time and it is at 4.5 milileters. Do I assume that this is a CYA of 45 ppm? Can I also assume that a fc of 5 on the test kit is 5 ppm? Does it seem reasonable for the he fc to drop very little over a weeks period with moderate to heavy use and some heavy rains? He did have some trichlor pucks in the skimmer which have now desolved and I do not plan to use them anymore. My ph has been rock steady at 7.4 to 7.5. According to the cya chart, my target tc should be 6 on the taylor kit. My olan is not to reach shock levels unless I have algae, CC >0.5 etc., and maintain level (6) with 6% clorox. Does all of this appear to you like I am on the right track? Thanks so much for the feedback.
