I tested by ALK yesterday after the change at 10-11 then last night I tested and it was 8 after some acid... I did some more acid after that so I am guessing its a 6'ish.... ph is otw up and I have added some alk back in also.
Im not gonna dose to crazy as I want to just change out the water and get rid of the problem down the drain....
but I want to 'zero' the tank over a day or two....
this is frustrating, I have better things to do today.
Anyone have such an issue with the apex before?
