When my wife and I built our first pond we invested in an external, non-pressurized type filter, and as it turned out, it didn’t work for us. We had some problems with it and I decided to try my hand at filter building. Knowing that surface area is a big factor in pond filters, I came up with my own homemade pond filter. I have a picture of it here and I’ll tell you what it does.
This is the kind of filter that we have been using for the last seven years and it works very well in our 3000-gallon pond. The pictures below will give you some idea of how it helps to keep the pond clean. The picture on the left shows a filter with a newly installed media ready to go into the pond. The picture on the right shows the same filter one day later. As you can see it collected a lot of junk. And even though the right picture appears to be really dirty, this filter can, and probably should, be left in the pond, at least for a few more days. I’ll try to explain why.
The filters I offer for sale are big on “working area.” You know, the area I was talking about back in the first paragraph, in conjunction with the “good “ bacteria. I offer two different size rolls of filter media. One has a “working surface area” of 16 square feet and the other has a “ working surface area” of 24 square feet. That is why they work so well. This is a pond filter that you actually don’t want to over clean because if you do you’ll be washing away the good
