Received my TF-100 today!
First test... Chlorine Drop Test... following directions I put 10 ml in the speedstir and added 870 powder. Looked like a tinge of pink so I started adding 871 to bring back to clear. Seems like the more drops I added the more pink the sample got. Washed the equipment and started to retest. Second sample put in speedstir beaker and added 870 powder. Looked clear so let it set for 15 or 20 minutes and came back and found sample had turned pink.
What have I done, what have I done?
Thanks for any help you can give!
