## Description

Fish Tank Filter, Silent Internal Aquarium Filter, Clean Water, Air Pump, Make Waves (4W-450L/H, Black)

## Features

- 🐟【Biochemical Filtration】This fish tank filter has 1 box with biochemical cotton inside, can collect and filter the waste in water, make wave and circular flow, help to culture beneficial bacteria, create a healthy water environment for your fishes and turtles. The biochemical cotton is washable and reusable.
- 🐟【Increase Oxygen】The air inlet on the aquarium filter will increase oxygen level of the filtered water, make the fish more active. Also, a good supply of oxygen helps culture beneficial bacteria like nitrifying bacteria. You can adjust the oxygen supply by spinning the valve of air inlet. P.S.: The valve of the oxygen inlet should be placed outside the fish tank and contact with air.
- 🐟【Ultra Quiet】Premium pump motor is noiseless during operation. It is only 35 dB, almost like the whisper or the sound in a quiet library. We recommend to turn off the spin button and stop the air inlet process at night, so that the filter pump will be more quiet. This way, it will not affect the operation of the filtration.
- 🐟【Easy to Clean】It is very convenient to take out the biochemical cotton and wash it, or your can replace with other filter medium. If you have any questions about our products, please feel free to contact us and we will do our best to solve your problems.

## Questions & Answers

**Q: My tank is 80cm l× 40cm h × 30cm w. we got the middle size filter but it seems to be too strong. would the small size be big enough for our tank?**
A: Mine is almost square and the 4w is doing a great job of stirring up my snails and Cray fish along with some overkill but I think it could do this 55litre tank alone,2might be better but that's almost a whirlpool situation going on.Good little unit,so far. Hope it's all shielded well seems ok but it's no interpet equivalent which is part of the overkill.

**Q: Hello I bought one of these today and it’s arrived but the instructions are very poor!! Does the tubing go inside or outside the tank???**
A: Hi, mine is inside the tank. I think it controls the amount of air that comes from the filter. Agree the instructions are not that clear but mine is working fine with it inside

**Q: does it come with filter sponge ?**
A: Yes it does it has a tubular filter sponge that fits inside

**Q: Instructions? There are no instructions and a very bent and twisted tube but no idea where it goes?**
A: If you are asking about the clear tube it fits on to the small hole and then you take it over the outside of the tank beside the cable plug it in then adjust the black piece at the bottom of the tube to regulate the flow of water hope this helps you
