I am intrigued by your design and thinking of making one although I am having no problems maintaining 30-35 ppm with my diffuser. I take it with the 3/16” CO2 supply tube you don’t really need an additional bubble counter do you?
For a 55 gallon do you recommend the 4” or 6”?
Thanks

Rio 180 it is.
The bubble counter is the tube itself.
Another reason I don't use separate bubble counters.
Clean that tank good, large tanks are not easy, make sure there's no light and also good conditions afterwards, clean the tank and the filter good also.
