getting a little concerned as I tested just now and FC back to 1. It was a very hot day here today, so hopefully that caused it. I used pool math to determine how much to put in to get to 9 FC and did that (about 210 ounces). I'll test now to see what it is.
OK, FC is 9. Lets see what happens in the AM

Great thread and it looks like you are on track for a TFP soon. FWIW, I have had my pool for three years. I found this site when I was building the pool and was able to learn about pool chemistry before the water went in. I used pucks until my CYA got around 35 and then used bleach to maintain FC levels. Muriatic acid and baking soda as needed. I usually test my pool on friday morning. When CYA drops I will use a puck if chlorine is low. If not I add bleach.

I run my pool year round. In 3 years I have had to slam my pool one time when I let the FC get close to 0 and saw some green on the walls. It only took a couple of days to get it clear again. I usually shoot for 3-5 ppm for fc. If we get a big rain, I may go out and dump a gallon of bleach in. My point is not to pat my back but to let you know the stuff these guys tell you really works. TFP has made owning a pool easy for me. I have never been in a pool store. I buy bleach and acid at Lowes. Once you learn the chemistry basics, it all makes sense. Sounds like you are figuring it out!! Enjoy.

Hi. I have been running my pump constantly for the past 3 days. I would like to do a oclt tonight, okay to let my pump continue to run? The video on your site says to run it for 30 minutes before the Morning sample, but if it is running all night that’s okay?

Good news, the overnight test showed no loss in FC. Pretty sure my loss during the day is due to my still high CYA, after draining 2/3 and refilling, of about 65, and sun.
