Two Take Pressurized CO2 Question
I will be switching my 29 gallon take over from DIY CO2 to a pressurized system over the next couple of days. Right now I use the citric acid/ baking soda method, and use a ceramic diffuser in the tank. My biggest gripe with DIY system is that I cannot keep it consistent, and have big swings. So here's to the pressurized system helping me achieve stability! This tank is running a penguin 200 HOB filter.
Now my question- I also have a 55 gallon take (current African cichlids) that will be turning over to a planted tank with rainbow fish, etc. I currently have a SunSun 303B canister filter with a pre-filter canister (SunSUn HW 602) that houses all the mechanical filtration (3 sponges and a 100 then 50 micron polishing pad). The main canister has 2L of MarinePure balls, and 2L of Matrix. With this in mind, I am not sure what would be the best type of CO2 device for this tank: Ceramic diffuser, inline reactor, or inline atomizer? I also have 2 wave makers to aid in tank flow. My hesitation on the ceramic diffuser is its lack of efficiency in a 55 gallon tank. For the reactor, I am not sure if the working pressure will be too high for it (due to the 29 gallon needing ~25-30 PSI for the diffuser there)
As I think about these different methods of dispersing CO2 in the tank, I think about what working pressures I will need from my regulator (Aquatek Premium). Right now I am going to start with the 29 gallon (do not yet have splitters & needle/metering valves for 2 tanks) but will quickly get everything running on the 55.
What has your experience been with multiple tanks and CO2? Also- attaching a picture of the 29 as is right now. Thanks for the help!
