I have a 3000 gallon pond with a Max-flo 2900 pump which feeds a 30 gallon barrell with 2 matala mats and then bio material, this feeds into a 150 gallon RM trough. I've been having to clean the filters on a weekly basis because it gets clogged. Sometimes it overflows because the filters get backed up. Temporarily i have it feeding right into the 150. should I ditch the mats? and leave the 2 laundry bags of bio material in there? suggestions let me know. Appreciate it.
