I found the test kit to be a little difficult. I'm sure it's because it's my first time. My test results are as follows fc=5 tc=5.5 ch=225. Ta=90 ph=7.2 and cya the black dot never disappeared but when I had Leslie's test this morning they said the cya was 30 fc was 4 ta was 0.2 difference ch was 120 Ta was 90 ph was 7.6. They said I needed to bring the phosphates way down and the ch up. But as I read on here phosphates don't matter and for vinyl line ch doesn't matter. I'm sure Leslie's test were more accurate than mine. I'm now worried weather or not I'm gonna mess up the chemistry due to my readings being way off. Also can I pour the test water down the drain?
