I'm looking into using this in an FX5 or Eheim 2217. Has anyone used matrix in either of these? If so what is your experience compared to biomax or Ehfisubstrat/subtrat pro?
You must not be using enough in each basket!josephjeon;4850364; said:OKAY! DO NOT BUY IT FOR FX5! I got a 4L bucket of seachem pond matrix for 40 bucks... and I DEEPLY regret it. It rattles and makes OBNOXIOUS noise inside the filter! I donated the 4L to my LFS....
