Please refresh my memory on FC testing

[coruna1]

Hi All!

Happy to be here again for another great BBB season. I just open my pool to a black swamp, started shocking and I' m using my DPD test but it only allows you to measure your FC level up to 5 ppm. I know there's a way to measure the FC much higher for when you're shocking, but I completely forgot I would really appreciate your help, I think I'm loosing my mind :grrrr:

Why not go ahead and get you a FAS-DPD chlorine testing kit? It would be much easier on you and would at least be accurate. You can buy the test separately at www.tftestkits.net.
