Description
400mm Diameter Full-Circle Wide Oxygen Coverage: Large 400mm round layout releases bubbles all around the ring. One ring covers the bottom of big aquariums, eliminates all oxygen dead zones without multiple small air stones
Anti-Rust Stainless Steel Fixed Frame:Twisted stainless steel outer bracket holds nano tube firmly, no deformation under long-term water soaking, rust-free for year-round freshwater use
Ultra-Fine Nano Mist Bubbles, Gentle For Sensitive Aquatic Life :Special nano air tube produces countless tiny low-turbulence bubbles. Won’t churn substrate, disturb shrimp fry or stress timid tropical fish
Circular Layout Creates Stunning Ring Bubble Curtain:Uniform surrounding bubbles form a gorgeous circular bubble wall at tank bottom, powerful oxygen supply meanwhile upgrading your underwater aquascape view
Durable Washable Nano Tube & Simple Operation Tips:Detachable nano tube can be rinsed to clear algae clogs for repeated use. Fully soak the ring in fresh water for 2 hours before installation; 12W+ air pump recommended for full ring bubbling
Upgrade large-volume water oxygen supply with our Round Stainless Steel Nano Air Diffuser Ring, professional heavy-duty aeration gear built with anti-rust stainless steel outer frame and solid brass metal air inlet connector. The circular aeration ring is fitted with high-density nano rubber air strip, secured by multiple stainless steel hanging buckles to prevent stripping and air leakage, perfectly designed for large freshwater aquariums, decorative landscape ponds, commercial aquaculture breeding pools and seafood temporary holding tanks for long-term continuous oxygen supplementation.
The nano rubber strip produces massive uniform ultra-fine tiny bubbles that fully mix dissolved oxygen through every layer of water, effectively activating water quality and resolving aquatic hypoxia issues for ornamental fish, farmed shrimp, fish and shellfish. Compared with small single air stones, this circular ring diffuser covers far larger water contact area, delivering more even aeration effect for big water bodies.
Crafted with corrosion-resistant stainless steel frame and rust-proof brass metal fitting, this pond aerator withstands long-term underwater immersion without aging, cracking or air leakage. The washable reusable nano air strip allows simple rinsing of sediment and algae for repeated use, greatly reducing regular replacement expense for aquaculture operators and landscape water feature owners.
Beyond reliable oxygenation performance, dense soft vertical bubbles form vivid dynamic bubble landscapes, adding unique ornamental effect to outdoor garden ponds and large display fish tanks. Equipped with multiple stainless steel hanging rings, you can easily fix this aeration ring at the bottom of your pond or tank. For the finest bubble output, fully soak the nano air strip in clean water for 15 minutes before connecting to your air pump. The universal brass connector fits most standard air pump soft tubing for quick, hassle-free installation.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $7 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Ortonia products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
