My life (and my fishes') with pressurized CO2 is now about five days old, and I still have yet to see the hallowed lime green drop checker, so am seeking advice on my next step.
I started off with the diffuser beneath the internal power filter (rated at 500lph), but this caused a lot of filter burping, a lot of bubbles of different sizes, and only achieved a blue-green on the drop-checker.
Seeing as the tank is small (67L) I have now moved the diffuser to the opposite end of the tank, where the outflow from the filter, as Richard from AE elegantly put it, catches the bubbles 'like a bird in a thermal'. You will see from the picture below how the bubbles are held down by the current:
But still, drop checker only gets to blue-green, its greenest being at the end of the day (I think).
Currently the bubble rate on the D&D system is over 1 bubble/sec, but I am wondering if I need to increase this?
Here is the positioning of the drop-checker in relation to the diffuser (note the blue-blue-green colour that I see in the morning, despite the gas coming on 45 mins before lights on):
And finally for you flow-nuts out there here is a picture showing the tetras hanging in the current that will hopefully take the CO2 laden water back to the other end of the tank:
Is it time to turn up the gas? Any help as ever will be much appreciated.
Thanks
Joe
