Hi Laing. Thanks for your reply. The system is an existing system. As per the original question, it has been running for 3-4 years at a low pH of 4-5. I am a new employee to this remote site. An island 4000km from Australia. There is no other treatment plant that gives me the ability to reseed. The plant has very poor settling characteristics. I am currently dosing NaOH to rectify pH. The PAC was getting watered down due to costs. I was asking for ideas on alternative reseeding
