If you have beginning algal growth, or any of a number of other issues, it could consume your chlorine very quickly. Don't be surprised at this. Continuing dosing with bleach until your chlorine level holds over night. That will indicate that the 'goo' is gone (oxidized or burned up). Once you reach this state of goofreeness (not to be confused with the state of enlightenment), you'll probably need to add some more stabilizer.
Thanks for the reply Doc. Question. How often should I be adding bleach and testing? I tested 40 mins after adding the shock dosage and it gave a low reading. when should i test? should i adjust my dosage? at this rate seems as tho i need a truckload of bleach!
