I'm using Ehfimech in the bottom, black Matala media next, Ehfisubstrat next, blue Matala media next and blue/white media pad last. Easy to clean. I just take the filter to laundry room, set on washing machine, open backflush drain into a colander set in sink (to catch any baby fish), open top, remove top media pad & pour pail(s) of used tank water to backflush.
What is backflushing and how do you do it? I've also noticed that there are 2 intakes for this filter? Sorry for all the questions this will be my first eheim filter if I buy it and im a noob when it comes to eheims.
