POLYBIO Poly Filter PAD 4 X 8

good

Ive tried so many different products, but this one is so far the best. It is pricey compare to active carbon, but it works better than carbon for sure. My water was clean before I replace my carbon with this one. After running this for a week, my water is crystal clean!!!!!! It worth the money!!!!!!

Works as described.

works good.

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 was really not too pleased with this product. I didnt see any noticeable positive improvement in my tanks water quality. And it just seem to get marked up with sediment regardless of it being in my final sump chamber. I personally think your money allotted for your aquarium hobby could be much better spent elsewhere.

Great product! Really helps with filtering out toxins !

I have a smaller tank of small shrimps with limited filtration, so having a small cube of the poly filter gives me confidence that my tank is good. I dont use this as a filter pad. I just let a small cube or two sit at the bottom of the tank. Shrimps seem to like cleaning algae bits off it.

I just started planting my tanks and realized the Activated Carbon in most filters was leaving a black film on and killing my plants. I tried so many other options, finally, I found these. They work great!

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