Poly Bio Marine Products APMPF 4 in. x 8 in. Poly Filter Pad

This stuff is amazing

Very happy with these, saved our fishes

I keep axolotls and my father keeps fish tanks. I was suggested to use Polyfilter by another keeper who also keeps a marine shop, as I had the odd problem with ammonia going up to 0.25ppm. He originally gave me Arcadia Polyfilter, and suggested I cut strips off and place it directly into the tank (I have PF filters which are much flatter and thinner than the Polyfilter is).I bought this hoping it would be as good as the Arcadia brand and I haven't been disappointed - it's cheaper, the same size and just as effective. I use it to ensure my parameters don't go up any higher than they have to, but it's also good for removing medicines and toxic chemicals from the water - it'll even tell you what it's removed by changing colour, with a guide to the colour and what it means on the back of the packet. Have no fear it will crash your cycle by removing ammonia for your bacteria to eat - it does no such thing. I have used it in my tanks for months and I have never had a cycle crash. It's good for tense moments - when you're not sure but something doesn't seem right in your tank - or to keep around in case your tank needs medicating.The only downside is that, as the last reviewer said, it gets used up quickly. My axolotls produce a lot of waste and, with water changes at 50% a week, it tends to last around a month before it goes black (i.e it can't absorb any more). It does say you can rinse it out, but I haven't ever managed this so I just change it for new.Overall, I count this as a good product to have and I haven't ever stopped using it since it was suggested but it is expensive and does get used up quickly (a piece this size tends to last around 3 months for me, if my father doesn't pinch any for his tanks).

I was a tropical fish shop owner for over 35 years and this product was invaluable and saved many of my customers fish. I always have one in my fish cupboard as a spare for emergencies. If your fish are showing signs of a need for a tank clean and you have not got the time. Place one of these pads into the tank either in your filter or near the return flow to absorb and neutralize the bad water.

Genius product, had an ammonia spike in tank, added this and within minutes could see if was filtering this out (turns yellow), after a few hours it started to turn tan indicating filtering organic waste. I attached mine above my sponge filters with a clothes peg (be careful peg doesn't rust) to enable maximum water flow over the filter media as this works best. Also added some pieces to my canister filters to help them out a bit also and as a fail safe to any blips in ammonia or nitrite levels.Highly recommended, if only to keep in your cupboard for emergencies ie filter fail or adding too many fish at once to tank (I am guilty of this as get carried away at fish shop). Will be buying more now.

lovely family owned business, quick and the product was as described. Lovely

This is good,and tells you by colour what is being removed by filter which is handy.I originally bought this to see if it would polish the tank water,it cleared the water to a certain extent and water parameters have been just right for over 6 weeks.

I have not lost many fish since using this in tank. Fish seem healthier and not doing water change just quite as often. The only thing is the price it is quite expensive. probably cheaper versions but not tried any. I have cut pad into 3 strips and use in tank seems to be adaquate for 120ltr tank.still floating at top of tank I still use my normal filters too.

Bien

Fantastic stuff ! Just a little pricey. Great for removing tannins from your water.

It saved our tank! Despite testing and regular water changes and all the care a couple of hobbyists a year in could provide, something bothered our fish one morning. They were all gasping for air at the top of the tank when I got up. I did a quick water change (luckily, we had enough water already de-chloramined and ready to go) and I also put in this Poly-Filter pad. The fish recovered and we didn't lose any of them. The pad did soak up something, not exactly sure what, despite the color coding. Great product, we have worked hard to get our tank healthy for our tropical fish and a die off would have been devastating for everyone, especially the fish! We'll be keeping these on hand and we plan to use them in a DIY protein skimmer project too. Also, hoping that these will help when we go on long trips and need to skip a water change. I got this after watching a Rachel O'Leary video (and Aquarium Coop too) and am glad I tried it.

I have been using this product for my old school under gravel filtering system for many years with exceptional results achieved in keeping the aquatic environment safe for all the marine life in my 55 gallon freshwater aquarium. The color change of this product over time provides clues as to the tank's overall health as well. In using this product, I have found that water changes may be extended...great for times when having to go on an extended vacation, as it keeps a safe tank environment without having to worry about unsafe conditions for the fish while away.
