Review on HiTauing Cartridges Replacement QuietFlow Aquarium by Kari Vena

I have a rooster. I clean the tank once a week. I ordered these filters and they fit perfectly, but after a week the filter was covered with sediment. They were supposed to last more than a week so I rinsed them out and used them again but the next week the tank was gross. There was shit on my plants and fixtures in the aquarium. I threw it away and used a new one (because I have a hell of a lot of them). In less than seven days, the entire first floor of my house smelled like fish shit. My rooster started sticking his head in the gravel. Before those filters, he was fine. That's the only thing that's changed. You can legally make him sick. EDIT: After I posted this review the seller contacted me and offered to fix everything which makes a huge difference in my book. Good customer service speaks volumes. I won't be buying these particular filters again but may check out some of their other products.
