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?

I was thinking of running it on the puffer tank because I think it would benifit from Co2 more than my main tank, I guess that FE would last a while on the puffer tank. I just now need to decide weather to order that regulator/solenoid or not
I am trying to find out what plants will grow in brakish water and look nice in the tank.
HAHAHA!!! FW Puffers all the way
