I have 3 Eheim 2260's and while I use different media in them, they are basically set up the same.īottom layer= Ehfi Mech (hollow cylinders), about 2 to 3 inches thick. What have people found to be the optimum arrangement? I'd like to avoid charcoal because it has to be replaced, but I'm wondering if thats the only way to fix my hard tap water that has a lot of iron in it. Then I found a good deal on substratpro and fix, followed the manual and put mech then substratpro then fix from bottom up, and my water is not very clear at all. When I first got the filter it came with leftover carbon from the previous owner and I ran only that and the ehfimech for about a month and my water was super crystal clear. Also, they dont say to use any type of really fine polishing pad or anything. With this recommended setup, all the crap gets stuck in the ehfisubstrat pro bio media, and the floss is completely clean. Second of all, has anyone noticed that the 2260 instruction manual says to put the media in this order from bottom to top: ehfimech -> efisubstrat -> ehfifix (AKA big mechanical hollow cylinder things -> bioballs -> green floss stuff)? First of all, what is the best arrangement of media and what media should I use for my 2260 on a 125 gallon tank?
