Pumps too powerful?

[wehtam]

Hey guys. Have a RSM130, with two maxijet1200. Wondering if they are too powerful cause when I turn them both on the water level drops and there is a ton of air bubbles coming through. Iv tried to add water but then the level in the display gets too high... And tips/advice would be greatly appreciated!!

Thanks, mat


Edit: nevermind. Changed the media filter and all seems well...
