Waterbear,
thanks for the comment. My CYA should be around 50. I have never been able to get a reading form colorQ more than 9! Retesting the same sample gave me different measurements and surprisingly the water seems to get less cloudy the longer it sits! Maybe it gets warmer. This was not apparent with the liquid reagent and the dot. Temp here is over 90 in daytime! I have followed the instruction to the letter using a stopwatch - I am surprised that lamotte does not ask to shake the sample but just turn it upside down three time and once before placing it back in the tester. the pool was plastered and filled in June. The only thing in the pool has been trichlor tabs, bleach, CYA(6 lbs), Muriatic acid and baking soda. temp 80, PH 6.6, TA 87, CH200, CL 3.8, CYA ~50. I hope there is something wrong with the meter since I really like it. I might even keep it just for the other tests.
Regards
Amir
