Hello, My small outside pond is a 3 tier setup (have not took pictures yet), 1st tier is a 20 gallon half-barrel HDPE liner in a half barrel spilling into a 50 gallon preformed spill way pond liner (2nd tier) and then that is spilling into a 270 gallon preformed pond.
Filtration is a 1,200gph pump going to a 13w UV pressurized filter then to a 30 gallon pool sand filter that is filled with Bio Balls, but I want to get a 5mm coarse sand to replace it on the sand filter and place all the Bio balls in the half barrel spillway liner.
The half-barrel liner has a 1"ID Bulkhead about 2" from the bottom with a 1" PVC 90 elbow to cause a swirl in the barrel and was wondering if I could use lighting grate to wedge 1" before the spill way and place my bio balls under that so they swirl and "Agitate" the media and if it would be beneficial or a waste of time? Thanks!
