POLYBIO Poly Filter PAD 4 X 8

best filter media available

it did whaaat i expected

Seems to work the way they say.

Exactly what I needed, works great. Thank you

Does wonders for the water quality of my axolotl aquarium!

One of the Finest first-stage Medias Ive ever used!

I have never tried to clean them out so I change the pad every few weeks once it has collected enough to look gross. Using has part of a multi prong approach to controlling nitrates

I had used many different products to try and solve our nitrate problem, but the polyfilter was the only one to work to lower the level. My tank had also had low, but nagging, ammonia and nitrite readings that lowered to 0 when I put in the polyfilter. I used the product in my Fluval 350 canister filter, slipped down on the outside of the large foam inserts. I took out my used up filter and the nitrate level elevated again. I am glad to find that Amazon has a three pack, since my local fish store only carries packs of single filters and cant keep them in stock. The only downside of this product is that it states that it can be recharged, but when I tried recharging per directions but it was no longer effective in removing the nitrates, etc.

I have been using this product for many years now, they are overpriced by the manufacturer but worth the cost considering the alternatives that flood the market every year. You can either waste your money on other brands of plain poly or you can spend more on these and know that your fish are well protected.

Great product! Really helps with filtering out toxins !
