Those who’ve been around the aquatic block for a while know that Under Gravel Filters (UGFs) are a testament to time. This Filter is air driven and utilizes an Air Pump (not included) to cycle crystal-clear water throughout your aquarium while keeping a crisp and neat look inside. This means there are fewer “moving parts,” making for simplistic and easy maintenance. It’s suitable for most 10-gallon aquariums and is safe for Freshwater and Saltwater setups. Biological, Chemical, and Physical Filtration: As air is pushed through the Air Stones and rises through the Lift Tubes, water is gently suctioned through the gravel and the filter plates, allowing both air and water to pass through the Filt-a-Carb Activated Carbon Cartridges. When water continues to be drawn through, anaerobic bacteria collect and colonize within the gravel and filter plates. Also Aerates Your Tank: Since the Clear-Free Premium Under Gravel Filter is air driven through the use of Air Stones and an Air Pump (not included), it also aerates your tank. In essence, your aquarium is being filtered and aerated at the same time, through the same system! It’s a filter and bubbler in 1! Items Included: The Clear-Free Premium Under Gravel Filter includes 2 Filter Plates, 2 Adjustable Lift Tubes, 2 Straight Airline Tubes, 3 Filter Plate Connecters, and 2 Replaceable Filt-a-Carb Activated Carbon Media Cartridges. Measurements: Each Filter Plate Separately = 9.5” (W) x 9.5” (D) / Filter Plates Together = 19” (W) x 9.5” (D) / Each Lift Tube at Filter Plate Base = 9.75” – 12.75”.
Just emptied & deep cleaned everything so can’t really tell if it’s doing good but so far it’s good. Michelle. US. Sun Sep 03 2023
