Does the PAP FC test cap at 5ppm - does anyone know?
I use the k-2006 test and my results are as follows:
PAP results as follows:
CYA 100 (this is their cap)
I attempt to keep my FC as per the pool math chart so it correlates with my CYA. My test reads 11 today as intended but pinch a penny gave a reading of 5ppm so I was thinking that perhaps like their CYA test they can't read get a reading beyond 5??
Also my calcium hardness is significantly higher and they wanted me to put in 27 lbs of increaser. I did not because I am not sure what to do. My pool's CYA was in excess of 300 a couple of months ago (calcium was fine ~250). We did a partial drain and refill to get it down and I never needed to add calcium after replacing the water (according to my tests) can that possibly be correct? I am thinking it *could* really be closer to 150 logically since replacing some water, but I have tested and retested (yes, correctly) and I am well over 200. My reageant for the CH test (blue drops) are a bit thick and gloppy - but it's new.
Had to buy chlorine anyway and wanted to get a second opinion on my CYA level- that darn black dot test leaves me guessing. Now most of my tests have me guessing......
