I have been reading and searching the forums on CO2
for my tank and I am sure I missed some good posts, but I would appreciate any feedback you can provide on my question below:
planted aquarium with Fluval FX5 canister filter running mechanical pad, carbon pad, and porous ceramic biological cylinders.
Running pressurized CO2
from a 10lb tank. Bubble rate was about 2-3 per second, just increased it to 4-5 bubbles per second.
I am also running two airstones at the other end of the tank from the FX5 return, about 60" away (5 foot long tank).
Therefore, there is plenty of surface agitation.
I have 20 Red tail rasbora, 7 cory catfish, 4 juvenile angels, 1 German Blue Ram, 1 clown plecostomus, 3 oto algae eaters.
(Yes, I got carried away and turned my serene, pastoral setting into a busy, thriving metropolis) LOL
I have a sand substrate, and a dozen low light plants. Tank has two T5HO lights and is very tall, > 24"...can't reach the bottom!
I dose with Seachem Flourish Excel and fert, about a capful or two daily (155g tank).
The plants are doing very well, so I guess my question is more academic than pragmatic in nature.
My PH remains at 7.6 despite the CO2
diffusion. Do you believe that I am losing CO2
due to outgassing from the fluval filter and airstones?
I don't know much about outgassing, so thanks for any info.
And yes, I plan to install a drop checker next week. I assume they work independent of size although I did see some categorized as "nano drop checkers."
Again, thanks for feedback on outgassing of CO2
