But my question is why would you want to shut off the CO2 at night. People that do that save a little CO2 from their pressurized setups, that's all. The plants don't benefit that much from lower CO2 at night.

the co2 levels that build up at night can harm fish ive been told. during the day the co2 is used during the photoperiod but at night the co2 isnt and builds up concentrations in the water which can harm fish. am i wrong or over paranoid about this?
