Best aquarium filter media for water purity. Keeps my discus tank water crystal clear as long as I replace it every 3 to 4 weeks. I buy the 12-inch pad and cut it to fit perfectly where needed.

Hi, unlike carbon which when full , leaches organics back into the aquarium. Poly filter adsorbs and bonds with various organics. It also changes colors until black and it’s exhausted. A little more money, but well worth the investment Thank you so much

The best chemical filter on the market! I have been using it for over 30 years. Everything goes in, nothing comes out. Overpriced, but AFAIK there are no analogues.
