POLYBIO Poly Filter PAD 4 X 8

Product is as expected.

Had an issue with cyano ( red slime algae ) and this filter took care of that in 3-4 days. I will continue to use this filter as it has made my water parameters much better. Highly recommend.

Keeps my tank looking its best.Controls algae really well. Definitely recommend 100% best filtration out there

I love this stuff works great in all BETTA tanks. No I do not have filters. Well I do have natural filters for them such as plants. This gives me a few extra days and I can also see what is going in my bigger tanks. This works great in the shipping of fish as well. All you need is a postage stamp size in the bag with the fish.

Price and removing copper from my tank

Excellent product

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

This stuff works great to filter the bio waste in my reef tank. I use this with a tri-layer prefilter and get great results.

My water levels have been good, but I added a piece of this to my HOB just in case.

Works as intended
