when i prime the pump ehiem proII external filter bubbles enter the tank,
i expect this, but after filter has been running 1/2 hour i get regular snow storms of bubbles can anyone help thanks
Are you restricting the flow into the pump at all? That can cause cavitation that creates bubbles... another possibility is that you are drawing too near a source of bubbles or the surface... that could also draw in air that gets turned into bubbles in the tank.
