Air Pump And Maxijet 1200. Pumping Air With Pump Off

Kris_sullivan

So I have a fluvall air pump that has 2 outputs. I have silicone hose going from each output to 2 separate maxijets (through the venturI port)

When the pump is off the maxijet is still getting air to cause bubbles. I have a check valve on each. I also have tried controllable valve with check valve. The controllable valve needs to be shut completely.

Anyone have any tips or ideas to try to make this stop?

Sometimes you want the bubbles and sometimes you don't? Is that right?

Yes. I only need the air going into the tank for a set amount of time. I have it on a timer.

Now when the pump is off the amount of bubbles in the tank is no where near when the pump is on.

The maxijets are just able to move the diaphragm in the pump enough to be annoying.

Seems like the only way to fix that would be to have the valve be controllable by the timer, i.e., use a solenoid of some sort. I got nothing.

My fall back plan is either to poke numerous holes in the tubing that is below the water line. But not sure that will work, and if it does, what issues might arise about algae forming in the hose around the holes.

OR

Just get airstones of some sort.

I've found the bubblers on powerheads to be pretty useless for one reason or another and have a couple of airstones in my tank.

Incase anyone sees this in the future. I had to cut a little hole on each hose under the water line leading to the maxijet. It puts water going through the tube so the maxijet is unable to get air from the shutoff pump.

That works too!
