I put enough cya in a sock 3 days ago to get me in the 70-80 range (swg) and I am still getting a reading about 30 or so. Should the reading be going up gradually, I started at 30ppm.
I read here it takes a week to get a good reading, do I need to be more patient? When do you get to a point when you just add more?
I did backwash a few times, but nothing drastic. I am shocking at a cya of 30ppm. Today my fc is 4.5, it was 10ppm on monday, I am going to add about 3 gallons tonight. Oh my cc is .5
