Video of the filtration of my koi pond. First you see the trickle filter with UV lamp connected. The trickle filter is full of ceramic media. There is siporax, crystal bio and KSB. The pump connected is a superfish pump 8000 liters at only 45 Watts!! It is a new type of pump that has very high efficiency and is very low on electricity cost.
Then there are 2 filter lines with bio media. The first chamber is a static bed the other 2 are moving bed. They run on airlift. The pumps use about 40 watts each.
