Help!
I ran out of Dichlor and am using MPS to bring up my chlorine levels. My problem is, my TC is 3ppm, but I cannot bring the Free Chlorine up. I have added about 1/4 cup of MPS and my Free Chlorine level still won't get above 1ppm. Do you think I should keep adding MPS or just go get some Dichlor?
All other levels are good.
Thanks
