Those who’ve been around the aquatic block for a while know that Under Gravel Filters (UGFs) are a testament of 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’s less “moving parts,” making for simplistic and easy maintenance. It’s suitable for most 20 (long) – 29 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 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”

My umbrella cockatoo seems to like it! I had to buy bigger washers for this because the ones sent just fall through. I advise that the manufacturer ask what size washers are needed and ship those! It would make the perch instantly useable.!. Kari. Wisconsin. Sun Dec 31 2023

This wooden cat hide-away is a perfect blend of style and functionality while maintaining a minimalist design.

This was a nice upgrade for my tortious, however I think it would have been nicer to have 3 panels of glass, other than 1, so he can see out. He is constantly climbing up on his rocks to so he see more. I think he will adjust . There's definitely more room for him to move around. The product is somewhat stylish and is made well.. Susan.

Cute little play center for our budgie Polly. Easy to put together and pretty sturdy. She hasn’t played with it yet, we’ve only had her for 2 weeks so still working on training and taming but excited to see her play on it once she’s acclimated. The wood, rope, and bell all seem in good condition, the only piece I don’t really like is the plastic toy piece on the rope. It’s very hard plastic and has almost a sharp edge that I need to file down so Polly doesn’t hurt herself on it. Otherwise very happy with the purchase! Shipping was fast and item was packaged well. When put together it’s exactly as pictured (the swing and ladder are not shown in my pic because Polly wanted to play with those in her cage lol).. Celeste. Mooresville, NC. Tue May 12 2020

Versatile and Adjustable Mounting: The provided 2.5” suction cups easily attach to glass, plastic, and acrylic terrarium walls.

Our Lizard Loungers can be placed at any height and location, providing an elevated vantage spot for your pet. Its versatility allows you to position it many ways until your little one is happy! Keeping Things Clean: For optimal use and longevity, our Lizard Loungers should be spot cleaned on occasion. This prevents debris and dirt buildup on the natural seagrass fiber. Use a vinegar and water mixture on the lounger, spot clean where necessary, then immediately dry completely before letting your pet climb back on. A hairdryer works extremely well for this last step. By doing this, your Lizard Lounger should live a lifetime, or two! Because of its longevity and durability, it can be used over and over in several terrariums! Gentle on Reptile Skin: Although our Lizard Loungers look rough and rugged, the seagrass fiber is soft enough for sensitive skin. When it’s time to shed, reptiles will rub against this natural fiber in order to remove old skin. Since our Lizard Loungers are made from natural materials and are handwoven, please understand that the provided measurements might not be exact, but they still should be within a difference. Create a Multi-Level Jungle Gym: We offer Lizard Loungers in several shapes and styles: Small Corner Triangle, Large Corner Triangle w/ Ladder, Extra Large, Sun Lover Basking Platform, Vine Backdrop, and Extra-Extra Large Bridge. Build a woven playground by purchasing multiple loungers! Use the leftover leather strips to connect them together!
