I am a new pool owner.
I have spend about 6 weeks and who know how much money at Leslie's trying to get my levels correct.
I was tired of the inconsistent results, inconsistent measurements, and the general sense that the people at Leslie's don't know what they are talking about.
I found this website and am giving it a try.
I just received my TF100 testing kit.
My biggest problem is I can not get any chlorine in my pool.
I measured my CYA at 30 (although the people at leslie's measured in between 0 and 90 in the past week). I have now stopped using the pucks in my chlorinator.
My pool is clear but since I have had several weeks of not being able to get a FC reading I want to SLAM my pool.
I went through the pool math and it said to add 3.5 gallons of 10% bleach (found this at leslie's). I put in the bleach, put the pump on, waited about 6 hours, retested the chlorine and still got ZERO (both with the OTO and my water stayed clear when I added the R-0870).
