I have been using the drop test with the powder everynight to check my Fc. After reading instructions it says you should do that test once a week and use the OTO one daily. After seeing how much of the powder I have and how much it cost im thinking I shouldnt use it as much or will be out fast. I have a hard time telling the colors apart on the yellow OTO test. I pretty much add the same amount of bleach a night so If I go over a little I should be ok. How do you all test everynight?
