POLYBIO Poly Filter PAD 4 X 8

I love this product! I overstocked my 50g cichlid tank and as a result had a constant problem of Ammonia spikes and very high Nitrate levels. I do up to 50% water changes weekly but the problem would quickly return within a few days. I heard about Poly-Filter on YouTube and thought I would give it a try. After the first 24hrs of putting the entire 4X8 pad in my wet/dry sump, the Ammonia went from 10ppm to 0. My Nitrate was also reduced by about 50%. I did another 50% water change which reduced the Nitrate to about 5ppm. After a month, I have no more ammonia spikes and my nitrate have been holding steady at about 5-10ppm. If you overstock, which a lot of cichlid owners do, you have to try this product!

Works ok. Took a while to get copper out of my tank.

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

Good product. Just as expected .

I’ve been using this product for years I highly recommend it over any other filtration material

Seems like a great product. Hard to tell.

works well

Keeping coral is no easy task, and if something leaches into the system it could take weeks to months for everything to recover. I have a very good filtration setup, but I also keep these Poly Filter pads, as insurance. They work great and change color depending on what it absorbs.

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!!!!!!

This filter makes your water cleaner and clearer than bottled. If you want a guaranteed way to keep your fishs water healthy and clean, use this filter.
