New member and pool owner. First thing is I am trying to forget about everything the pool liars told us when they were taking our money for the pool. We were sold on the frog system. I got a test kit and after about a week or so I noticed the water looked clear from the surface but was cloudy underwater. With the frog they say .5 FC. I reset the frog and hold the FC at about 5 and the water is clear now but my CYA is 50 or 55. I can just barely see a dark ring at 50 and just goes cloudy at 55 so I might bee looking at it wrong. Anyway I am dumping the frog and going BBB. I sent my wife to the store for bleach. She comes back with several 96oz bottles of Hill Country Fare regular bleach for $1 each. That's from HEB grocery for the ones in Texas. The sodium hypochlorite is not listed as a %. Is there a way to mix a small batch to see if it's 6%?
