View Full Version : Biocube 29 bulkhead size and fitting a Rio 6HF pump

I'm not at home right now but I just got a Rio 6 HF pump to upgrade the stock pump. Looking at the Rio output it will need a 3/4" tube and if I recall that's larger that the stock pump tubing. So does anyone know what the stock bulkhead fitting is for the Biocube 29? Will I need any reducers?

i would directly connect the hose to the bulk head and forget the 90 degree fitting.

Its either 1/2" or 5/8"... I forget. But is the Rio gonna fit in your chamber 3? I remember researching replacement pumps and there were very few that would fit. That chamber is pretty small / narrow.
