How Do You Measure Co2?

[Beemeeup]

i am introducing to a new tank co2 to assist plant growth.

is there need to measure co2?

how do you measure it? - i have seen a kit which is an upturned bottle hanging in the aquarium with an indicator on it - quite expensive for the relatively short time it lasts - 6 to 8 weeks i believe.

i am keen of having a heavily planted 175 lite tank and to try and ensure the plant life is a good as i can make it.

any help would be useful.

You'll need to know the pH of the water, and get a test kit that will measure the Kh.
Then use the website above and it'll tell you the CO2 levels.

BTW be warned that adding CO2 will lower your pH (become more acidic). Just making sure you knew

Thanks for that - could you tell me what is KH please?

I can see from the article i need a KH testing kit - thanks for the advice - one more lesson learned!

The test kit will mention KH (and probably GH).
KH is carbonate hardness.

Taken from the site:
Working to raise the pH of the water is the KH. While KH refers to Carbonate Hardness, what is really measured by a standard KH test kit is really the buffering capacity. In "most" water sources, the buffering is provided by Carbonate. In that case, buffering capacity and KH are the same thing. Assuming a constant amount of CO2, a higher KH, will result in a higher pH.

Not sure what it is in simple english though
