I have a euroreef skimmer rated for 135 gallons. It comes with a sedra powerhead with needle wheel venturi injector. My question is this does sedra incorporate in thier powerheads anywhere a foam filter??? My buddy said that they do and I just cannot see from looking at the pump in the sump where a oam filter would be located. My concern is if it has a foam filter acting as mechanical flitration then it is a nitrate trap. Do any of you know if my buddies claim is correct????
