    Fas-dpd testing

    OK guys easy on me here I'm woman lol so little bit clueless. I just tested water using Taylor k-2006 fas DPD kit. I used the 10 ml sample water because my little dipper said 0.05 on it so I assumed this was correct thing to do. After testing and multiplying drops x 0.5 I came up with 8.5 ppm for fc and 0.5 for cc. Are these numbers good lol?

    "Good" is a relative term.

    Your FC level is dependent on your CYA level. If CYA is below 100, then, yes, you're good. http://www.troublefreepool.com/conte...art-slam-shock

    It's a bit high for a pool with no CYA, but still low enough for swimming in.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.

    If you check that FC/CYA chart you'll see you're a little high on FC, which is wasteful. But you're still below shock level.

    You never want FC below 3 with 40 CYA, and when you dose, aim for 5. When you recheck it the next day, if you're below 3, then target 6 the next day. If you're losing more than 4 in 24 hours without a bunch of kids or drunk adults to blame for it, then you have a problem.
