well... the filter does its job and turns the water crystal clear after a couple of days of running... but when I shock with dichlor the water returns to apple juice.
While remaining a mystery, I have an idea: there is some dark brown "build-up" in the in-line frog - which my dealer had said was nothing to worry about. My guess is that the increased level of chlorine is "releasing" the build up in the PVC line into the water - although... bromine and MPS never had this effect.
Any ideas?
txwillie, all well with your switch to dichlor?
