Dkh

Mike:

Thanks Mike I will try shutting my reactor off for now. I have also read that adding vinegar to my top-up tank will also add some acidity to the system. Thanks again

It's normal the effluent out of the reactor will have a high dKH (20+) so if it was only 10 before doesn't really seem like it was running properly.

As to bring the current alk level down, just shut off the CO2, I wouldn't be adding anything else.
