Is there any downside to using this chemical to reduce chlorine quickly?
After killing black algae my friends levels are 24 ppm chlorine and they want to get back to swimming with their dogs in the pool.
They do not wish to wait for it to go down naturally.
What I really mean is that after being the Super Pool Hero who got rid of all their black algae I do not wish to look bad by killing their two "Darling" little dogs!
Although come to think of it life would be a lot quieter!
