How to test daily when FC target is over 5?

Hi all

I've successfully been using the TFP method for five years now and test my pool regularly using the FAS-DPD test in my K-2006.

One thing I've never been able to figure out is the daily vs weekly test methodology. The idea is that I should test my pool daily using a simple test kit and weekly with the FAS-DPD kit.

I'm running a SWG in a pool that gets nearly full sun all day. I have my CYA around 60-70, and for whatever reason I need to keep my FC at the upper end of the range to keep the water sparkling.

So with a FC target of 5-9, how do I effectively do a daily test when all the basic OT kits max out at 5ppm?

Welcome to the forum. Pretty sure I've never used my OT test kit. You should be able to get that SWG dialed in pretty good so you don't have a need to test daily unless particular circumstances arise. (Big Party and such".
