Premium Koi Pond Filter Media Roll - High-Efficiency Pond Filters for Outdoor Ponds, Reusable Fish Pond Filter Material, Made in USA (PRO - Blue - 4ft)

Good value. Good product. Quick ship.

Easily rinsed and reused. Very clear water and very happy goldfish and koi.

Last year someone bought property uphill behind my 3800 gallon Koi pond and cleared off a lot of brush and grasses - that lot is now just dirt, much of which is washing downhill and into my pond. The water got so thick with dirt I could only see the fish when they surfaced for food. I have 375 gallons of filtration that had always kept the water clear and healthy; the tanks became clogged with mud and the weekly cleanings weren't making a dent in the mess. I decided to try this along with my regular filtration. 3 weeks ago I got my first two 10-foot rolls; put it as an extra layer in my mechanical filter and the filter at the head of my stream, into the skimmer box, wrapped the pump in the bio-filter, even around the exit tube in the vortex for the first few days. I've been kept very busy pulling and hosing tons of mud off this material, but it's working! I ordered another couple of rolls, changed the configuration in the mechanical filter where I have an upright "wall" of this material (preceded by several layers of matala), followed by 100 micron felt pads, and another layer of this material, and today the water is clearer than I can recall it being in several years! I'm *very* pleased with this product! My only complaint is that it does deteriorate fairly quickly under many and hard hosings. But now that the mess is gone I'm sure this will help keep things manageable without having to hose the crud out of it every couple of day. Highly recommend as an addition to regular filters/biofilters to keep the water cleaned up of floating gunk! The pix I posted aren't the best, the lighting was too bright, BUT you can see the bottom, and the lily pot on the bottom - which is 5 feet down!

This floss is way thicker than the others I have seen. Works way better!

This filter is great for my koi pond. Before I added this filter, my water could not get clear. After adding this filter, my pond water is much clearer. I will be purchasing more filter mesh in the near future. I would highly recommend this product to anyone who has a pond.

Breaks down fairly rapidly after a few rinsing.

Easy to cut, bargain price, sturdy, does a great job filtering...

It looks exactly like the previous filter material it replaced. Seems to do a good job of filtering. I've discovered that if you leave extra material out too long the birds like to try and make nesting material from it

Used this filter in a skimmer. It did catch some stuff but the white side started falling apart after a couple of cleanings. Was not as fine or tightly woven of a filter as I had hoped for.

Used once and fell apart. I am trying to get a refund now.
