My mistake, it took 2 drops of 871 to turn it clear and then after the 5 drops of 0003 it turned pink and took 2 drops to turn clear again. So it would be multiplied by .5 , I divided by mistake. The FAS-DPD kit is from TFP. As per the pool store test just now , there is 0.0 FCL and 0.5 CC ,there was .1 FCL and .6 CC yesterday. Does this mean we are on the way down ?? As far as TA it's 105 and Hardness is 170. It does look like we are heading down , but the FCL has been being used up very quickly ? Thanks
