I want to use the venturi valve application on my new powerhead but I cant seem to get the water to stop coming back up the hose which is stopping the air flow. How can I get the water to stop getting sucked up into the hose ? thanks.
is the airpump on before the powerhead is turned on? i had to turn the airpump first then the powerhead or it'll get into the airline. also you might need a more powerful airpump depending on the power of the powerhead, how deep it is under the water.
