cheapest reactor isnt a reactor at all...use a power head in the tank with a airstone in the intake. thats what i use in my 55 heavily planted. works like a charm. just my 2 cents

Is there a way I can test my Co2?

You can use a drop checker or consult a pH / KH chart (although the chart is even less accurate because of tank variables).
