Review on PULACO Aquarium Internal Filter for 3-20 Gallon Tanks: Ideal for Turtle, Reptile, Amphibian, Frog, Cichlid, Newt, and Fish Tanks by Adrienne Holmes

Item received damaged. Part of the engine cover was cracked and just floated on top of the crate, it still works fine but it's always annoying when something breaks. . Also, we don't have a hanger in our box, and it says it's included. The suction cups work well but I would prefer to hang them up. There are no assembly instructions, but everything is quite simple and easy to understand. It has good water flow, so I don't recommend it for small aquariums. I have a 5 gallon tank and it churns up the water so much that my fish go mad as they swim around to avoid the current. I would recommend at least 8 liters. So I turn it on for about an hour a day and then turn it off so my fish don't swim all day.
