How much CO2

[robo-snickers]

Whats a good indicator for how much CO2 you should be adding to your tank via pressurized C02. Right now i am pushing about 2 bubbles per second but when I look at my diffuser (a class one from CO2 art) the stream of tiny bubbles doesn't seem like that much... I man there is still a stream of bubbles just not as much as i normal see on youtube. is this normal? and when do you start noticing change with the plants in the tank? I only have CO2 running for less then a week, Thanks... oh and my tank is a 72 bowfront.

I recommend a drop checker at minimum. It will help tell you what concentration of dissolved co2 you have in the water.

I wouldrecommend you invest in drop checker also.
Many just swing their ph 1 whole degree while lights andco2 are on.
How long are you rrunning the co2 for?
Here is a kh/ph reference chart;

Heres a link to DC and the 4 dkh solution you must use!!

Regular API pH reagent will work with the dc but you have to have 4dkh solution for them to be accurate(no matter what instructions say!).
