Description of 🐠 Ultimate Penn-Plax Clear-Free Under Gravel Aquarium Filter for 20-29 Gallon Tanks – Fresh and Saltwater Safe!

NOTHING LIKE OLD SCHOOL: The Clear-Free Premium Under Gravel 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’s less “moving parts,” making for simplistic and easy maintenance. This filter is suitable for most 20 (long) – 29 gallon aquariums. BIOLOGICAL, CHEMICAL, AND PHYSICAL FILTRATION: As air is pushed through the Air Stones and rises through the Lift Tubes, water is gently suctioned through 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 collects and colonizes 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, though 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 = 14” (W) x 11.1” (D) / Filter Plates Together = 28” (W) x 11.1” (D) / Each Lift Tube at Filter Plate Base = 13” – 16”.

Goor Filter: Filter Accessory

Overall this is a great gravel filter. But the plastic pieces you have to remove to combine the filter for a larger tank are awful to remove. You'll need something like a dermel drill with a saw blade to remove them. This is the only bad design feature.

Pros
  • Handy Item
Cons
  • Factor Set

Great for the price but requires tools and intelligence

This worked great in our 39 gallon bow tank. Assembly instructions were included. not enough, but we found out. You will need small scissors or wire cutters to cut off the protrusions. Trying to use your hands is useless.

Pros
  • Best in Niche
Cons
  • Some Cons

Great filter. Save your $ and buy it!

Experienced fish breeder with 7 aquariums, of which there are more. Few companies still make them and I applaud Penn Plax for carrying on the tradition. Affordable, reliable, efficient and low maintenance. Another common brand uses a domed top for riser covers. These are people with air, releasing a "bubble” about every minute. Penn Plax has the best shape for flow and stillness. Aquarium filters are like politics. Everyone has their own opinion, but very few do their homework. The classic UGF…

This gravel pack changed the world!

I have three large fancy goldfish in a 29 gallon aquarium and it has been very difficult to keep the water clean. I have used traditional mounted back filters but when I pumped the gravel, changed the water and filtered the water became covered in bacteria which left the water white for days and I just couldn't get the water to circulate properly. with good conditions for fish. I watched a YouTube video that said I should try a gravel pack. I am new to the fishing hobby and need help. With a…

Pros
  • Absolutely amazing!
Cons
  • Damaged

Here is some information that is not in the description.

Exactly as it should be. FYI, this comes with 2 carrying straps. This information was not in the description. Also, there is no information in the description that it comes with 2 Filt-a-Carb cartridges that fit in the top of the tubes. However, if you zoom in on the item, you can see this information on the packaging. And just a note, if you want more lift tubing, I recommend getting the Penn Plax brand. Because of the way they connect to the record, Lee's brand doesn't really work. I mean you

Pros
  • Hard wearing finish
Cons
  • Annoying
