hi,
i was just wondering, i have a fresh water tank with lots of live plants and a few fish.i'm using pressurized CO2. the CO2 is off in the night because plants dont absorb it in the night, they absorb oxygen. this mean that my PH level in the day is a perfect 6.7 and at night it goes up to 7.9(thats when the CO2 is off).
now, is that BAD for plants and fish? or is that normal?
PS. i'm thinking of getting 2 DISCUS fish and i hear that they high maintenance fish so will this affect them in a bad way?
THANK YOU.
