I have been testing my water locally from a distributor of Dazzle products. I have clear water with a hint of greenish/yellow in the deep end area. It is very subtle. I tried putting 900g of lithium pro shock last night and it cleared up the water a fair bit, but still has a hint of discoloring. Surprisingly, I tested the water today and it shows I have 0.1 free chlorine. I keep chlorinating pucks in the chlorine dispenser and turned the knob on full. Any reason why I am not seeing chlorine levels increase? I suspect chlorine needs to be between 1-3ppm in order to control and kill algea, assuming that is what I have in the pool.
