Hello, all. I'm setting up my first planted aquarium and I'm a bit confused about the technical set up. I've read that CO2 reactors can be set up in-line with canister filters, but I have yet to find a detailed description of this process. My assumption is that since my CO2 bubbles will be broken up by the reactor, it would make the most sense to attach the reactor to the output line of the filter. How would I accomplish this while maintaining a water tight seal? I would assume the hoses will be different sizes; how do I compensate for this?
