Title: Nice Aquarium but very poor filtration
Review: I have two of these aquariums. One in each of our kids rooms. We loved the Hex shape and size of the tank. We filled each aquarium with distilled water. Each tank has one betta and two cory catfish. We have never been able to get clear water from either of these tanks. I am not impressed with the filter or bio wheel system. It provides little circulation and more water appears to go around the filter cartridge than through them. After waiting two months for the water to clear I plan to try an internal filter to see if I can get better results. I also tried the polishing pad and carbon bags idea but water remains cloudy. I've tested for ammonia, nitrites and nitrates and all appear normal.
