When simultaneously used in multiple applications, it will lose air pressure. Is this a new wand? If not, check for calcium deposits blocking the pores. If possible, you may also want to shorten the air tube length by bringing the pump closer to the water line. It takes more pressure for the air to get to its destination when the pump sits below the aquarium. And, if you have a check valve installed, which I always recommend, make sure it is not clogged.
