I should have listed more information.
THE DATA:
Indoor pond, 8 foot long / 5 foot wide / 2.5 foot high
Underwater pump to pump to 55 gal barrel filter, with a TEE at the top to split off a line and run to Bio-Tower.
Both filter and Bio-Tower will be fed water at their tops an then drain back down into pond.
What I need to know is , is there any need to clean a bioTower?
The reason i ask is that if I make a bio-Tower as suggested with the 6" or 8" sewer pipe and mount it to the wall I will have no way to clean it later.
Also, I was planning on the use of metal straps to strap the BioTower to the wall, is this a good idea?
Any photos of this or any other means to hold a 8" pipe in position?
Also, due to a lack of money here I was planning on the use of Pot Scrubbers as the media inside the BioTower...good idea ?
