Aqua-Flo 12" Pond & Aquarium Filter Media, 72" (6 Feet) Long x 1" Thick (Green/White)

Background: My 1,000 gallon koi pond suffered new-pond syndrome with a bloom of planktonic algae late this spring as pond temperature rose above 60F. While water tests showed that beneficial bacteria had established, the suspended planktonic algae remained making the water dark brown/green. After waiting four weeks with no clearing of the water, I purchased this filter fabric and added two layers to the skimmer box behind the skimmer net and large strainer filter fabric and two layers of the fabric in the waterfall filter box just before (upstream) the bag of bio balls. I found no issues with the pump sucking the skimmer box dry, so two layers of this fabric in the skimmer and waterfall (4 total layers) still allowed water to easily flow through. Performance: After two days, the water began clearing up considerably. I pulled the fabric out of the skimmer box and rang it out by hand to find a massive amount of dark brown/green water/algae trapped in the filter. After rinsing and replacing, I left the fabric another two days, and the water has cleared up even more to where I can now make out objects at the bottom of the pond (3' deep). I rang out the skimmer box fabric to find, again, a ton of brown/green water/algae trapped. At this rate, I expect the water will be cleared up within a week or two. The fabric shows no signs of decomposing, tearing/fraying, or having issues being rang out. Conclusion: Excellent product since all the resources I read said skimmer filter fabric will not catch suspended planktonik algae. I will be running this filter fabric all season long since it is performing so well.

Nice media no complaints

Very best filter material for the 12"x 6" box holding the fountain pump in my 300 gallon outdoor goldfish pond. It is easy to cut to size.

Worked well

I bought this for a secondary filtration for both my fish aquarium and also outdoor man made pond. It's durable and super easy to use! Just cut the size you need and place it. Ive definitely noticed the water clarity is so much better in both and super happy with this product! Definitely worth buying!

I use this as my Koi pond filter material, I cut to fit, washable too.

Good quality

I will start with the shipping. Over three weeks, Indiana to Idaho. To be fair to the seller, that isn't his fault, I just want people to know that I waited for weeks. It seemed to drop off the face of the earth. Tracking said it sat 8 days in/near Chicago, but that doesn't account for all the other times it just...disappeared. Other things ordered at same time came in 4-5 days, so this was an anomaly, sure. I wrote to finally just ask for a refund (even AMazon said it looked like my parcel was missing) and...well, I got 'schooled' on "the new post office policies" and it sounded more like a rant than anything empathetic for a customer whose money you have for a product they've not received. And that IS on the seller. What he said is probably right (that the new post office general has decreed that parcels can just sit in distribution centers and wait, while they make sure letters get delivered on time) but it was more a rant about that, and less about customer satisfaction in SPITE of the post office's admittedly crappy service on this one. So I took a star for that. The other star I deducted for is that this is NO WAY an inch thick. Be prepared for the parcel to be FAR smaller than you anticipate. It's possibly a half-inch thick, then rolled snugly together (hence the smaller package). It arrives in really good shape, it looks like really nice stuff, and I think it will do a GREAT job. But I think the advertising is misleading. Perhaps if I put a piece in the dryer to fluff, it'd bulk up to 1" but I doubt it. I am pretty happy with this, as I do feel it'll do what I need, but I wanted people to be aware of the ACTUAL thickness and that shipping - if it's crazylong like mine was - will earn you a less than understanding reply.
