Hi,
i have always had difficulty in maintaining c02 at a good all round level throughout the photoperiod.
Im currently experimenting with c02 to try and maintain peak levels (regards livestock) throughout my photoperiod without distressing the fish. I understand the light, c02 relationship and this is purely based on maintaining a level of c02 which will the suit the fish, then adjust lighting as necessary for the plants health.
Im currently starting injection 2 hrs pre lights on to get to a level of c02 for lights on which is at the maximum of fish tolerance without distress. If i leave this injection rate to continue throughout the photoperiod, levels rise further and the fish are effected. I have tinkered endlessly throughout several tanks and cant seem to find the happy medium. I am now experimenting using my timer and solenoid to switch c02 off/on at 15 minute intervals for the rest of the injection period which stabilises the ph (and c02) at the peak level. Im using an inline diffuser which creates a mist, but also gives good levels of dissolved gas.
Are there any negative effects from doing this? Im guessing if the dissolved gas levels are good the plants will still have access to c02 during the 15 minute periods without the mist?
Does anyone else do this or have experience of this method?
Cheers,
Ady.
