Thanks Randall. I have inherited this system a few months ago. No testing equipment, not pH probe, no chemicals, nothing. Recently I had a grease trap overflow into the system which has added to the problem. For the past few weeks I have been manually dosing lime mainly for alkalinity and also NaOH. Today I saw a pH of 7.09 in my main aeration tank and 6.97 in the decant aeration take where my stages happen. Today I installed a dosing pump to dose NaOH into the main aeration tank to no longer manually dose and to also have a good regular dose maintained. I am waiting on test gear to test for nutrients and alkalinity . It really has been a dogs breakfast , I hope I am making inroads . My first goal was to reach a good pH of about 7.2. The only problem now is that I work on a roster which is 3weeks on 3weeks off, the other workers have no understanding so I am worried I will be back to square 1 when I come back. Hopefully the lime addition will go some way in preserving my pH . I appreciate your advice. Thank you
