Is This To Much C02 In My 55g Tank?

[Batmanjay28]

I have 2 2L bottles going and a Hagen natural plant growth system thats good for 20 gallons of water. This is with the recommanded doesage.

Am I over doing the C02 in my tank?

If so what should I do? Would I have to take one of them off?

And, what about having the C02 running at night.....is that going to harm my fish?

Do you know your current CO2 level... You can buy a testkit which will measure CO2, the recemended dosage is 25 - 30ppm...

If your fish do suffer from the CO2 at night then adding an airstone may help.
