This is my filtration system. A submersible pump pumps 900 gph (turnover three times per hour) to a pressurized filter with built in UV, biological and mechanical filtration. The filter is the 1400 model, both filter and pump are from Laguna. I believe both together in a package were around $380.

Also as a note, ALL electrical equipment is connected to a ground circuit fault interruptor. I have two three-outlet GCFI units, one on each side of the pond. The UV, pump and air pump go to one unit. The dual 500 watt heaters (next picture) go to the other unit.
