Re: [APD] CO2 and Planted Rift lake tanks



Just means that a pH controller with an upper limit near 8 is contraindicated. But there are better/cheaper ways to dose CO2 than to use pH controllers.

Wouldn't adding CO2 to an African tank not be quite risky as it will
lower the ph?  Although I guess using a ph controller and probe to limit
the CO2 released in the tank but then I guess you'd not get much actual
CO2 released at that point to maintain a ph of 8.2-8.5?

Subject: [APD] CO2 and Planted Rift lake tanks

I have been reading past posts in the Archives about African planted
tanks and see there are some that used CO2 in them. Is anyone currently
keeping a planted rift tank and using CO2? I would like to hear how you
are doing with it now, tank parameters, fish, plants, lights, CO2, pH,
etc.

I have never used CO2 in any tank. I just recently realized it could be
used in an African tank when I read about it in the thread called
"Tanganyikan Planted Tank--A quixotic dream?" started by Erin Poythress.
This thread is dated April 27, 2004. Back then I ignored most of the
posts on CO2 as I didn't care about it. Now I am curious.

I looked at the CO2 charts and thought it wasn't possible to get any
meaningful CO2 dissolved in the water at pH 8.2-8.5. I am thinking it
would be in the single digits at the most. Am I wrong?

Thanks
