The Asian style Undergravel Filter Box is a unique way to filter your shrimp tank. It works by pulling water slowly through the media to the bottom of the box and pushing it out the tube at the top. This allows for a large amount of media to be used, and due to the water slowly passing through it ensure that the media or soil always stays oxygenated and that no dead spots occur.
Due to the lower resistance of the filter, it allows for a much higher flow rate when compared to a normal sponge filter. These filters have been tested to filter an average of 10-30gal. If given enough pressure and air, the filter can reach almost double the flow rate.
We offer 3 sizes of Undergravel Filter Box:
- 4”x4:x4” Suitable for 5 Gal tank
- 75”x4.75”x4.75” for 10 Gal tank
- 8”x4”x4” for 20 Gal tank
A great advantage of the filter is that it requires minimal maintenance over its life span. It’s recommended to only clean the filter when you restart your tank, or if your soil buffering capability has run out (Normally 1-2 years). Replacing them is as simple as removing the box from the tank, removing the content, giving it a rinse and then filling it back up. If you have a backup filter that has been pre-cycled you can instantly replace it in your tank to keep on running.
The Undergravel Filter Box is a box you are free to experiment and optimize as you wish. You can add any media or soil to it in any quantities. If you are looking to buffer your water and are worried less about biological filtration, you can fill the entire box with buffering substrate. This will still provide biological filtration, as a large amount of bacteria lives on your substrate.
This filter kit includes:
- Filter box
- Airline tubing.
- 1 Airstone.
- Filter plate
- Higher adjustable tubing (Maximum height 15”)
- Coarse foam pad
Kindly note that this kit does not include buffering soil.
Due to it being handmade please expect some minor differences in the finish of it.

UGF BOX
Overall quality is really well done, I first bought one and then realized shortly afterwards that I was going want/need another. Only complaint is that the the two don't match each other. The lift tubes/heads are different. It's nitpicky I know, but from an aesthetic stand point I wish they did. I'm giving it a 5 star rating because they're still done well and I'd buy it again.

Must have in a Shrimp Tank
Very easy to assembly and I really love it was able to plant a Anabus plant and it's Beatiful. My shrimps are very happy and with the right substrate helps keep Ph down. Also let me tell you it's really hard to find this filter in the USA.

Asian style UGF
I had seen these all over YouTube and wanted to try them out without DIYing it. Found this site and can report that the box is great. Shipping was fast and I'm going to order a few more for my next shrimp tanks.

Awesome UGF Box
I purchased the 8x4x4 size and it is perfect for my caridina shrimp tank. Entire ugf kits are hard to come by, so I couldn’t be happier. Great pricing, high quality, speedy shipping, and communicative seller. I plan on buying more kits when I eventually convert my other shrimp tank to ugf. 5 stars!
