Correct me if I'm wrong but it doesn't seem like Eheim Ehfimech has a lot of surface area or serves much purpose. Is it just a cheap space filler?
It is claimed that Ehfimech traps coarse waste particles and disperses water evenly for subsequent layers, wouldn't a simple sponge or a few stacked sponges work better and have more surface area?
I'm thinking about getting rid of the Ehfimech in my Eheim 2217 and either use more filter pads or Ehfisubstrat Pro. Currently I have Ehfimech on the very bottom, sponges, then 2L of Ehfisubstrat Pro.
Please let me know what you think.
Thanks in advance.
