    Basic testing with FC of 6

    I currently have a CYA of 50 so my FC needs to be between 4 and 8 with a target of 6. The K1000 test only goes to 5. I was wondering what anyone is doing to test for an FC of 6 besides using the true test for FC. It would be awesome if I could just use the K1000 kit to test the FC and pH each day and then do the "real" test once or twice a week.

    The TF-100 is a custom kit put together for EXACTLY the purpose you are describing. I have a dog in the fight, but you are describing your needs that will fit perfectly.

    Eventually you will settle in to a very predictable rhythm of chlorine addition. At that point the OTO test will be enough to verify daily that nothing has gone horribly wrong with your chemistry and the FAS-DPD test for once or twice a week for more accurate numbers. Until you find that rhythm though using the FAS-DPD test daily or every other day is best.

    I currently have the TF-100 with zero complaints. I just wanted to see if anyone had a secret to using the "daily" kit instead of using the FAS-DPD kit everyday.

    I typically use 2ppm per day. I do not want the FC to drop below 4 but the OTO only goes to 5. If I have it at 5 and loose 2ppm then I am below my recommended lever by 1ppm. I have no way of knowing how high above 5 I am with the OTO test... Does that make since? Do I need to do both test everyday until I can recognize the color of 6 instead of 5? Just looking for options.

    Just make sure the Oto test has a dark yellow and you probably are fine.

    Thanks... I may just take a picture of what it looks like at 6, 7, 8 and then compare to that when I use the OTO test. At least it would give me a guidline.
