Thanks for the reply. Yeah I will have to get a kit to measure the KH since
I don't know that value. I will for sure stagger the CO2 kits so that I
will always have a steady supply of CO2.

I can't wait to set this thing up. I have never had a planted aquarium
before. Should be tons of fun...

Ok. That is good news. I wonder why people keep telling me that my pH
will
swing around when putting in CO2. They keep saying I will have to
stabilize
it...

But if what you are saying is true, then I won't have to worry about it
any
longer. Good news for me.

As others have said a small/slow PH swing won't hurt your fish. A couple
of
things to consider though.

The Hagen units will run for 2-3 weeks - I would start one and then wait
7-10 days before you start the other. That way you will need to change one
every week or so and I think you will get a more stable level of CO2/ph in
the tank

Secondly the Ph you get to will be a product of 3 things

a) The Kh of your water
b) The amount of CO2 you put in
c) The amount of CO2 that is dispersed by surface movement/airstones etc.
If
you are finding you can't get enough CO2 to stay in the tank its probably
because you have too much surface moevemnt so try reducing this a bit
before
you go adding a third canister....

hope that helps
