Here the CO2
is a bit expensive. I run the CO2
to come on about 1 to 2 hours before lights and turns off about 15 minutes before lights do.
My canister filters turn off (somewhat) when lights come on so as not to increase CO2
off-gassing. This is because my tunze co2
reactor runs at maximum to get co2
into the water when it is on. I still have an internal powerhead / filter running almost all day to push water around plants.
Tank ph will start at say 7.2 or so and drop to say ph 6.5 or so (and then come back up as CO2
Must go and look at the reaction again.
