Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I doubt it. You would need to take out the venturi part and air tube. Then use some adapter to connect the pump. To much flow it would probably overflow from the top and not enough flow nothing will happen.
