Im preparing to put my first pond into my back yard and so I've been researching for a very long time and what items I should use for my pond. From what I've read both a pond skimmer and a bottom drain are musts for ponds with near by trees and fish in the pond which my pond will be. The problem is that I only want to buy one nice filter instead of two less functional and cheap filters and one high power above ground pump is there any way to combine both pipes leading from the pond skimmer and bottom drain into one central pump that leads to the filter, the pump, and then out to the waterfall or jets. Does anyone know if that is possible, and if it is possible which pump and filter would be the best to meet those needs. The pond Im planning on building is suppoes to be about 3600 gallons of water.
