does anyone know if the eheim air pump products are a good make and reliable ?
no.... i bought an eheim 400 airpump and within a month started to rattle and make very loud noises, i sent it back and was sent another brand new one. after about 2 months it stopped pumping air from 1 of the outlets and only very small amounts from the other....i was sent a tetratec 300 in replacement on request.
this is only my experiences with eheim air pumps and im sure lots of people have good ones but ill never change from tetratec again, i dont know why i ordered anything but tetratec in the first place as they have never let me down yet and are also the quietist ive had too
