I have my pressurized CO2 system just about up and running.
I have a 5lb aluminum CO2 cylinder from beveragefactory.com (due to arrive today, at which time I will take it to a local welding supply and have it filled).
I have a dual-guage regulator from beveragefactory.com
I have a Clippard MNV-4K2 needle valve from marinedepot.com
I bought an aquamedic bubble counter from a new LFS I found yesterday, which came with six feet of airline tubing that's supposedly safe for CO2 (according to the gentleman running the store).
Now, I don't have enough money for a solenoid or PH monitor as of yet, so for now I'm going to do without. Herein lies my question:
Do I need to stop the CO2 at night? This guy at the LFS told me I needed to in order to avoid rapid CO2 accumulation, and I'm positive he's perfectly knowledgeable about everything -- you should see his store.
However, I've read otherwise, and just wanted to know what everyone here recommends. It seems to me if I shut off the CO2 at night, there's going to be big PH swings. It seems to me if I keep the CO2 going at night, there's going to be big PH swings (because the plants won't be using the CO2 at this time).
What do I need to do?
