You need to know what your CYA level is--and then raise your chlorine to the "shock" level for that CYA reading....see the "best guess chlorine chart" linked in my sig for explanation and the chart (you may have to log out to read it until Ben finishes upgrading your registration). Hold the pool at shock level until it clears and you are no longer losing chlorine at night. Continue to dip out all the solid stuff that you can in the meantime.
