Do i really need to turn off a small DIY CO2 at night?
i have a 42 gal aquarium with 2wpg lighting. my tap water comes out around 4-5 KH with 7.4ish ph giving me somewhere in the neighborhood of 5ppm co2. i added a red sea 1 liter yeast system just to bump up the co2 a little bit. i didn't expect this system to get me over 10ppm so i'm wondering if i even have to bother shutting it off at night? i doesn't seem to start up right (the little pump that disolves the co2). it really has a hard time getting going in the morning. also should i run an airstone at night? do i need to even bother?
thanks any advice would be appreciated.
