Review on COODIA Internal Aquarium Submersible Disinfection by Maricruz Cosentino

From all the rave reviews I was very pleased to have purchased this product but the excitement was short lived. These filters have been in my aquarium for a week. now, and they haven't done anything positive for my tank. In fact, all of my aquariums have deteriorated with these filters. I double checked each one to make sure the UV lamp was on, as was she. I checked the flow on all of them. I even have this in a 29 gallon tank and my water has gone from almost clear to brown. I'm not sure if most of the other reviews are fake, but these filters did absolutely nothing for me. The $17 submersible filter filtered the water much better than this one. Luckily I can get it back and invest in something better because my fish deserve it.
