I have a 16 intex frame pool.the water is cloudy.if I keep the kids out of it for a day it clears up.I am using the BBB method.I'm using a cheap walmart test kit.my cl reading is 3 my ph is 7.6.I haven't gotten a good test kit yet so not sure what my cya is.I have been using chlorine pucks most of the summer and have read on here it will raise your cya.Today I took a water sample to the local pool store,guess what they said? shock it with the bags of shock...... ask them what my cya level was they said it don't really matter.so I guess time to order a good test.I vacuumed it good for the first time this summer,will see what it looks like in the morning.I think I really need a better pump and filter.
