Opened the pool with zero last year and zero this year. I tried to get it to 30ppm last year but I never got it even close to 30ppm I guess. After reading about pucks and too much CYA I scared my self in not putting much in the pool. How much stabilizer does a manually dossed pool need. I started off adding enough to get me to 40ppm this year. After being in the pool for a day, the sock I was using had a blow out and about 1/4 of it fell in the pool. Pulled the rest out and brushed to clear what fell in the pool. Got a new sock and only added 40oz this time. I have more in this year because the solution is getting cloudy unlike last year. The dot just disappears all the way to the top of the tube. How much is the very top of the tube? I usually dose to 4.0ppm chlorine every day. It is usually 2.0ppm or above every day so far this year. Yesterday was cloudy and was at 2.8ppm when I checked it at 9:00 p.m. What is normal loss for this time of year? Just trying to figure out how much I need.
