I can't get my effluent ph down!!!
I have a MRC dual chamber. Just changed my media in my first chamber to Schuran media and I have ARM in my 2nd. My effluent drip won't fall below 7.0. It has almost been 4 days. What's the problem? I don't want to put too much CO2 in the tank. With ARM it wouldn't take anytimne for the ph to fall. with ARM my C02 bubble count was 1ble per sec. With Schuran I have to run almost a steady fast stream and the cO2 runs all day. Is this normal or should I go back to ARM?
