Co2

How much is the right amount of CO2 to put in a tank. Is there a specific recomended amount. Wanna get set up us soon as I have planted my tank.

 

I guess it depends on your plant growth, mine is usually around 6'd

lets see what the experts have 2 say...

 

Ok CO2 how does this work? What do you need to put this in your tank?

 

6 d ?

 

Have a look at this, it should explain most of your questions http://www.aquariumplants.co.za/co2.htm

 

The kh/carbonate hardness in my thank..

 

You can maybe look into something called a "Drop checker". Very usefull thing that stays in the tank to give you a co2 indication.

 

Where would I find one of those in Cape Town?

 

So water hardness determines how much CO2 you inject ?

 

Yes. But with a drop checker, you make up water with a specific hardness and the aquarium water hardness doesn't affect it. Thus you don't need to know your water's hardness.

 

What would be a desirable hardness for a community tank? Mainly tetras.

 

How do you test for hardness??
Never bothered to try.....
