So I'm new to testing, received my TF-100 two weeks ago and have been reading on this site and following the info on the packet that came with the test kit. Today was my weekly, I realized that after I ran the K-1000 OTO test, so immediately (within 5 minutes of the OTO test) grabbed some water for the drop test. On my OTO it showed that I was in the 5-10 range (which I was okay with as my CYA was 50 this morning). However, we I tested using the drop test, I only had to add 7 drops of R-0871 to return my water back to clear from the pink (R-0870) test. When testing for CC, water turned clear after 1 drop of R-0871 (which if I understand correctly is essentially zero CC).
However I was surprised that there was a large discrepancy between the two test and makes me worried using the OTO style test daily to monitor my Chlorine level. I was assume the drop test is significantly more accurate.
Anyone have similar experience or have any suggestions?
