Why don't more people dose CO2 this way?
I have my CO2 line directly under the canister filter intake. Nearly all the bubbles get sucked into the canister filter and the filter acts as a reactor for the CO2. Every now and then I get a big bubble of CO2 that burps out but I still feel that most of the CO2 is getting dissolved into the water efficiently. Is there any reason that more people don't do this?
Ammonia and nitrites are zero. So either the plants or the canister filter is doing a good job of filtering a heavily stocked system. In the near future I'll add an inline CO2 diffuser to allow the bubbles to dissolve faster and so I can crank up the bubble rate higher. Plants are starting to look like a jungle and keep sucking up the CO2 faster and faster each day. I've tried getting atomizer diffusers but they are not efficent enough to keep up with my plant's demands. Still saving up for an inline diffuser and maybe an inline reactor also. The bubble counter is around 3-4 bubbles per second and I might be increasing that soon.
