If you just filled it, by all means go ahead and add the stabilizer -- 1 or 2 lbs in a sock.

If you water is clear, adding 1/2 gallon of plain 6% bleach should do you -- but you can't quit while you wait for the kit. Get a local OTO kit and skip adding bleach ONLY if the PM chlorine level is dark yellow.
