I just bought a Rio 180 powerhead for an undergravel filter. I have looked through the instructions, but I am unable to find the answer to this question. It comes with several attachments/accessories. The two I am wondering about are the 'Discharge adapter with Venturi jet and flow control' (which includes an 'Air stopper') and the 'Air tubing and silencer'.
I am under the impression that I should be able to get the powerhead to add air bubbles into the tank, as well as providing more flow through the UGF. I thought removing the Air stopper from the Venturi on the Discharge adapter and adding the Air tubing and silencer was supposed to suck air through the Air tubing and silencer and mix it with the water it is pushing around the tank. I find that instead, water dribbles out of the tubing.
I have had to choke back the flow through the powerhead to reduce the turbulence in the tank, but even when it was wide open, it still didn't really make many bubbles.
Am I missing something here?
Thanks.
