I just received my TF100 yesterday. Here is my first results.
FC 0 or less than .5
I tried to do the chlorine drop test, the sample never changed to pink when I added the r-870 powder. I continued and when I added the R-0003 it did seem to be "slightly" pink, and after 2 drops of R-871 it turned back clear. I am really confused by this test, I dont know where I stand with it, if I have a little FC or not. Just three days ago my FC was 2, do not know why it is dropping. My water is crystal clear, however I know that if there is no or too little FC that can change quick. I have bleach 6% on hand, but I am nervous about adding it and causing the metals in my water to redeposit to my walls and steps! Just got that resolved with the AA treatment a couple of weeks ago. How should I go about getting the FC up without ending up with metal stains again exactly? I have the pro-team metal magic and last added the maintenance dosage about a week ago, but need advise on keeping the metals in the water if I have to shock using bleach. Any advise would surely be appreciated.
