Diy Co2

I am looking at setting up DIY CO2 but I am a little apprehensive.
There are a few questions I need to ask

1) What do you do at night. I know you can't 'turn it off' and taking out is stupid but won't the water have too much CO2 in at night if the plants don't need any to photosynthesize?

2) In terms of pH, how much does it normally affect it?

3) What is a pH crash?

4) anyone know any good pH test kits from the UK?

5) anyone want to give me any advice. I really wanna go with the DIY as I don't have the money to go pressurized, but I am worried it could turn out horribly and I don't wanna kill my fish.
