Product Description

Lee's Undergravel Filter is the key to providing a strong biological filtration system. Undergravel filters utilize your tank's gravel substrate as a filtering surface area while providing oxygen to help aerate your aquarium water.

  • Provides biological filtration & aeration to aquarium
  • Includes airline diffusers, carbon cartridges, Discard-A-Stone & fish-saver feature
  • For use in fresh & saltwater aquariums

Placed on the bottom surface of the aquarium, the filter plates utilize the gravel bed as a source of surface area for bio-filtration and provide oxygen by recirculating the water down through the media and up through the uplift tubes.

The advanced design allows separate plate installation and features optional flow-thru setup, which can be used with a powerhead. Adjustable 1" uplift tubes provide superior water circulation. The filter is made of special, premium quality plastic which resists splitting and cracking.

Note: Must be attached to an air pump or powerhead (sold separately).

Lee's Undergravel Filter

This under gravel filter seems to work very well so far. The reason I gave this item 4 stars instead of 5 is due to the difficulty in assembling it. Otherwise I would recommend this product.

Aquarium under gravel kit.

Excellent product. Fits my tank perfectly.Instructions for assembly of the filter pieces woefully in-adequate however. Needs better description of how to cut out tabs between panels and how to stretch the pieces of tubing to fit over the pegs.Once assembled it works very well.

Everything I ordered was A+

The Lee underground filter, the Whisper air pumps, the Jaeger heaters all work as best as can be expected!!!

Another fantastic product from Pet Mountain

I placed an order for a large Under Gravel Filter. I honestly thought that the product would only come with the bottom grates, and maybe some tubes, but I was wrong! Not only did it come with all the nessesary parts, but it actually came with additional parts so that it gives you a few different options for setup. I opted to add standard shipping and it came just as ordered. It's so great having a company that you can trust not only with customer service but that carries grade A products. Thanks again Pet Mountain!

Lee's Under Gravel Water Fliter

I started using Lee's Under Gravel Water filters in the late 1990's. The units have a simple design, easy to assemble and changing filter medium is a snap. They are great, and do an excellent job. I would recommend Lee's to all my friends. Good quality and excellent prices.

Works fine

The filtering system is good.

Not what the package says

I purchased two of the filters listed as being (6" x 12") but they are actually only (5" x 10"). A bit disappointed but I'll keep them.
