Rated 5 out of 5 by Oldfish9 Flow better than expected PF-40.
Contrary to other reviews the flow is better than expected and very very quiet.
In order for the UV light to work efficiently the entire flow cant go through the UV chamber. It would be too much water volume to fast to sterilize properly.The water flow (GPH) of the filter will eventually turn over the entire tank many times during a hour treating all the tank water volume. It is also equipped with a flow adjustment to accommodate tank size and the flow you want. As long as the UV light is on its doing its job. The filter cartridge comes with washable mechanical media. Time will tell with long term use but for now its the best UV filter for the price. Don't buy from any one but the DRs. Shipping is excellent no broken parts.

This filter is great! It is easy to assemble. I like that it is clear so you don't have to guess what is going on inside. I think the UV light will be a nice added protection from disease and algae blooms. The only issue I have with it and for that matter most aquarium products I have purchased recently is the inserts give terrible directions. Its like reading a puzzle. Why can't they make it so it reads step by step ?? That being said it is great!

Rated 3 out of 5 by MagicMan Insufficient Flow
The filter is reasonably priced however I think the design could be improved as the UV light assembly does not allow the full capacity of the pump to pass through the filter causing water to back up and spill back into the tank from the overflow. Removing the bio media and replaceable filter cartridge does not improve the water flow. The design of the replaceable filter cartridge is fantastic as it allows you to add any type of resin or carbon and simply replace the cartridge filter pad when it gets clogged with debris so the operation of the filter as a whole is very economical and versatile.
