Review on 🐟 Lee's Original 15/20 Undergravel Filter: Superior 12-Inch by 24-Inch Filtration System by William Lara

This item arrived well packaged and very quickly. Assembling the filter is easy, with precision fitting and quality parts. The kit includes two 12" x 12" filter beds, each with an air hose hole. Two height-adjustable air hoses with activated carbon filters that snap into the air hoses. Two air ducts complete with plastic diffusers (bubblers) and corresponding air duct fittings, as well as air duct fittings made from hard transparent plastic and two air duct sections made from transparent PVC. There are two very short vinyl hoses (about 1/4 inch long) that are designed to connect the filter plates to plastic pins protruding from the bottom of the black plastic filter plates. They are used when you cut panels shorter or at an angle. Please note that these filters do not contain fiber or mesh filters.
