I just started BBB for my Intex pool. Do I still need to "shock" or just keep up with the bleach when the chlorine levels drop? Not sure if it makes a big difference I usually have 8-12 swimmers in the pool daily.
It depends on how you test. If you have a good test kit, you can test for Combined Chlorine. Anything above 0.5 CC indicates the need to shock. Normally you just need to keep your chlorine from dropping and you won't need to shock. Another indication of the need to shock is an increase in chlorine consumption, especially overnight when there isn't any loss to the sun.
