crazy CO2

[konrad05]

I was wondering if anybody else has experienced extremely high CO2 readings with a DIY yeast CO2 system. I checked my CO2, and after only a day and a half the CO2 is at 40ppm and possibly more. I have the bubbles feeding into the powerhead intake every few seconds. Tank specs are 55 gal, KH=4, pH = 6.5. Help! will it affect the fish in any way?

 

[Silly me]

anything over 30 is high, it might not do much to the fish yet, but the extreme amount of CO2 does change the PH of the tank so much in a short time it could cause a problem, also algae will over run the tank in no time as the plants cant use all that CO2

I would really look into to PH if I were you, as 40ppm will turn into carbonic acids CO2 + H2O <--> H2CO3 , meaning PH drops, the longer its not used the more the PH drops , and drops and drops and drops..

The mix should slow down after a few days, i've found it really hard to keep the co2 level/ph stable with my DIY setup, so i'm probably going to have to remove it when I get more sensitive fish.
