Opening the pool a few days ago.. Was told today that phosphates were high and also a 2 of ammonia. I forgot phosphates were not an issue and bought the phos free and added. UGH! Suggested to add 12 gallons of 12.5% tonight all at once to get rid of ammonia and come back to re test on Monday. I am still new to BBB but feeling I should be doing shock process instead!?
CYA assuming none given ammonia issue.
