Trying to get my mind around all this; maybe y'all could help. I'm
setting up a 400 gallon pond with a waterfall; total head 5'. There is
no room for a filter at the top of the falls. I'm considering building
my own mechanical/biofilter; please advise: Intake at the low point of
the 30" deep pond will be with a covered, submerged 5 gallon bucket
filled with lightweight filter media. Next in line a PondMaster Mag
Drive pump (PM-7, UPC 02527), that pulls the water through the 5
gallon bucket, then pumps it up to the falls. Falls pass through 2
small "puddles" with plants for veggie filtering. Think this'll work?
Is it feasible to 'pull' the water as opposed to pushing it? Thanks in
advance. PS I could imagine 2 of the filtering 5 gallon buckets inline
if 1 isn't enough...
