Why I get nothing done...
Since, I'm a newb, and just started really paying attention to the Alk in my tank, I've been adjusting my Calc reactor to try and achieve the correct Alk in the tank. Originally it was low at about 7Dkh when I first started paying attention to it. I've increased my CO2 bubble count on the reactor which quickly raised the Alk in the tank to around 12DkH. So then I reduced the CO2 and the Alk dropped to about 9 in just a day or so in the tank. Should the Alk fluctuate that quickly in the tank? What causes the Alk to drop? I believe the target Alk is 8-10DkH? Thanks for any input.
