Review on Poly-Bio-Marine Fish Aquarium Filter Media Pad, 3-Pack, 4” x 8”, by Poly Filter by Dana King

The best filters on the market! I've been to a few aquariums to wear them and sell them for $15 each so these 3 packs are a lot cheaper. These filters helped me when I realized you couldn't get a replacement for my filter set that came with my tank. Also, I have well water and was struggling with acidity so I had to use a sachem neutralizer to stabilize it and they removed all the bad stuff from the water as well as phosphates etc from the water caused by the sachem product , and helped me stabilize my aquarium. They also help with natural waste and ammonia! I have a slightly overfilled tank so I added air stones and switched to these products and I have no problem! I do water changes and vacuum every two months and replace it when I do. Keeps my aquarium crystal clear and balanced! The best product ever!
