POLYBIO Poly Filter PAD 4 X 8

Works well

I tried EVERYTHING to solve my brown algae problem. Nothing worked. Every time I cleaned my 50 gallon tank, the brown algae came back. UNTIL, I found this product. It cured my brown algae problem almost instantly. Easy to use. No extra reactors or stuff like that. So easy, I just dropped it into my Tidal 75 filter after a good tank cleaning and I have never had brown algae since. It is a permanent part of my filter media.

i am using it in my sump to see if it works better then the sponges i have now

good

We use these in a 92 gallon bow front, salt water reef tank. We use two HOB filters and we always have these in one of them. Works great and keeps all of our coral happy.

I have a problem with iron in the tap water from my house. Whenever I would do a water change on my tanks, they would always end up looking cloudy for a few days because of the iron. I have a Fluval 50 filter on my 36G aqueon tank, and I cut the poly filter pad to fit into the filter as an additional filtration stage. It works amazingly well for getting the iron out of the water quickly, keeping my tank clear.

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

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.

This should be in every fishkeepers arsenal, it removes toxins and will actually show you what toxin it removes by its color. For example tannins is not a toxin but if you put a piece in with a tannins or organic matter it will turn brown from it removing it, for copper it will turn blue and so on. Im currently medicating my fish and afterwards I will just put a piece in and let it help remove the medication. If course I am going to do a water change after medicating but this is extra insurance.

Yes, all the previous positive reviews are totally correct...within reason! With this dynamite mechanical/chemical filter youll elevate your murky aquarium water to a pristine and super transparent state....for an astronomical fee. I would absolutely not recommend Poly-Filter for hobbyists with chronic multi-tank syndrome. I currently own 4 aquariums and will probably rarely if ever purchase this amazing product again due to the exorbitant cost per tank. Another problem with Poly-Filter is its lack of longevity. I inserted this in my Penguin 150 Biowheel for my 20XH tank with only 9 fish and 2 nerite snails on a Wednesday evening; and by the following Monday morning, it was utterly exhausted...thats just ridiculously swift. In all the time Ive used various mech filter pads, Ive never had to discard them in LESS THAN A WEEK! Keep in mind this setup is only 2 months new, with well established bio filtration and not even overstocked. My former mech filter was finally exhausted and my tank was surviving only on bio filtration for almost a week, hence my current experiment with Poly-Filter. Yes this is absolutely a WONDER FILTER/CURE; but at its rate of exhaustion, Id be out $45 a month on this filter alone and thats just for 1 tank....NO THANKS. For the ongoing future, Ill somewhat ignore Poly-Filter and resume using Value Pack - Poly Filter Floss for $9 every 3+ months. I plan on eventually doubling the amount of aquariums I own thus increasing my need for the ultimate bang for buck products.
