I'm bubbling the CO2 into the bottom of my trickle filter, where
it gets dissolved as water drips over the bio balls. This seems to
work fine -- there's no problem getting high CO2 concentration --
but I have to wonder what effect this has on the aerobic bacteria
in the filter. I'm testing 0 units (ppm??) NH4, NO2 and NO3 with
my sleezy Aquarium Pharmaceuticals test kit, but I've got additional
biological filtration from an Eheim canister, so maybe all the
bacteria in the trickle filter died long ago and it's now just a
glorified reactor!
Anybody have any thoughts on this? I'm running ~20 ppm CO2.
