I have been messing with cya trying to not use as much bleach. I raised cya from 40 to 60 and seems like im using more bleach now than before. I had to ad 61oz of bleach tonight and 57oz last night to around 4000 to 4500 gallons of water. that seems like alot to me.. I thought i was using alot when I was at 40 cya and I was averaging around 50oz's a day. i will raise fc to 9 and be at like 2 at night. I have done a drop test and been with in .5 everytime. I would get it to 7fc at old cya of 40 and only drop down to 1.5 or 1 fc and now at higher starting point fc im dropping to the same. is this normal or what. seems like im using alot of bleach.
