POLYBIO Poly Filter PAD 4 X 8

Great product

The best media out there.

Love this stuff. It does what it says it does. Just wish it wasn’t so expensive.

Its a little pricy but works great. I put some of this in my aqua clear filter and my water is clean and super clear. The shipping took over a month. The product is great, the sellers shipping arrangements are not. That and the price is why this gets 2 stars and not 5.

still the best product for crystal clear aquarium water and removing harmful organics

seems to help.

This is a must to clear the water of any medications used recentally or at least once a year to make sure to pickup anything the skimmer cant or whatever else you use. There is no substitute for this product anywhere. Truly a perfect filter that never takes out minerals or any needs life just phosphates and protiens, amonia etc. that you want to remove. IT lasts a while with color changing properties to aid in evaluating when it is full. Never leaches back into the water ever! A++++++++++

Wonderful product. Always clear water... and good for the fish!

I have used this for years; it will filter your tank water better than most other filter media.

After having 3 bags of purigen break in filter I went back to using poly filter and get the same results of clear, cleaner water with no danger of microbeads polluting my tanks! Well made!
