I am trying to get my pH down to 6.2 and notice that it requires me to have the effluent bubble rate really high, like 3 bubbles per second. Is this normal? I have noticed that the more bubbles, the louder the pump gets and it gets me worried as I don't want to burn it out.
I have the drip rate around 40/min.
Any of you had to change the valve on the drip rate? Mine seems to not be super stable as I have to watch it daily to make sure it doesn't stop dripping. Im thinking about switching the cheap valve out for another and any ideas would be useful.
