I wonder how much of pool shock can I add to the reservoir?
I read that poolshock has 68% of active chlorine but contains 99% calcium hypochlorite. For calculating the chlorine amount in the solution (ppm) will I use 68% or 99%? I guess 68%.
How does too much chlorine look?
Will chlorine accumulate somewhere, maybe in the medium (e.g. rockwool) or will it dissipate?
And when can I readd chlorine without overdoing it?
