Hi everyone,
I have almost convinced myself to purchase a pressurised Co2 system, (and have included list and links to what I am looking to buy in #4 post) I would like to use a solenoid so the Co2 is turned off at night to minimise Co2 wastage. The only thing I am worried about is the PH swing that will be caused as a result of the Co2 being turned off and on every day
Please can someone with the knowledge advise me if the daily swing in the PH would be enough to harm the fish at all?
