    High chlorine

    Hi all,

    I received my new reagents for the tf-100 kit and tested everything.

    The FC came up to 12 with CYA at 70 the normal levels according to the pool math are 5-7 so I decided to turn off the cell until in the target range then to adjust the cell duty. For the pas two days I lost les than 2ppm of chlorine. I started to wonder if there is something wrong. All other levels seems to be in the target zone exept PH at 7.8 but here I learned that above 10 chlorine the PH reading is not correct.

    Please advise if this situation is normal or I have to do something. I want to make sure that all is good in next 7 days since I am goin on vacation for 2 weeks and don't want surprises

    Thanks

    12 will be fine for your pool, you're way below slam level. Just play with your cell settings until you have it right. I would keep it at 8 fc

    For a SWG pool, the levels are actually 3-5ppm (see the FC/CYA Chart) ... the key is to never let it drop below 3ppm. I would try to dial it in around 5ppm.

    But as said above, 12ppm is perfectly safe.

    A 2ppm drop is a little lower than I would expect if you have a lot of direct sun on the pool ... but nothing wrong with that.
