I recently treated my pool with absorbic aid to clear the stains on the vinyl liner caused by the use of copper algaecide. It did a great job clearing it except for the fact that i am havin a great deal of trouble keeping the chlorine up. its been 8 days since i treated it. i keep checking and rechecking the chlorine throughout day. it dissapates once the sun is out. it will be between 3-5 in morning then by 1pm its at a zero. my levels are all in line CA 30-50. It seems the AA is continuoulsy neutralizing the chlorine. how long will this take to maintain proper chlorine levels? i dont want algae. thanks
