FZONE Aquatic Glass Lily Pipe Set with Skimmer Inflow and Outflow

The FZONE kit includes both skimmer inflow and outflow pipes, plus a spring brush for maintenance. Made from laboratory-grade borosilicate glass, the set’s floating portion and the lower unit use durable acrylic to allow adjustable flow ratios. The skimmer inflow automatically adapts to water level, helping remove surface film while maintaining steady circulation. Rotate the bottom part to fine-tune surface flow for your aquascape.
Suitable for canister filters, this kit emphasizes a nearly invisible glass inflow that preserves the aquarium’s visual focus. The surface skimmer reduces buildup of dirt on the water’s surface, while the adjustable flow helps maintain healthy gas exchange and nutrient distribution. The build quality supports long-term use in hobbyist setups.
Hygger CO2 17mm Lily Pipe With Inflow and Outflow

This Hygger kit provides a complete 17mm lily pipe setup with an included cleaning brush. The 17mm outer diameter matches 5/8″ ID tubing, ensuring compatibility with common canister filters. The upgraded inflow features wider water intake slits to draw from a broader water column, while the glass body supports a balanced, moderate flow ideal for aquatic plants and some surface movement.
Designed to optimize water circulation and gas exchange, the Lily Pipe promotes even filtration across the tank. The included brush helps keep internal passages clear, reducing buildup and maintaining consistent flow over time. The kit’s compact form supports a wide range of aquarium styles without dominating the view.
FZONE Aquatic Glass Lily Pipe Set for 1/2″ Tubing

This FZONE set features borosilicate glass inflow and outflow pipes with a floating, acrylic-based adjustment unit to balance surface extraction against deeper intake. The surface skimmer effect helps remove the dirty film at the top of the water, while the bottom section’s rotation controls the rate of surface flow, supporting both plant health and filtration efficiency. The kit is a practical choice for mid-sized tanks using 12/16mm tubing.
Auto-adjusting inflow helps maintain a steady water surface, contributing to improved gas exchange. The glass construction offers a nearly invisible presence in the aquarium, letting the aquascape take center stage. As with other lily pipes, regular cleaning maintains optimal flow and reduces clogging in hard-to-reach areas.
FZONE Glass Lily Pipe Inflow With Surface Skimmer

The body is crafted from high-quality glass, while the floating skimmer section uses clear ABS acrylic. It is designed for use with a canister filter and features an auto-adjusting surface skimmer to remove top film. The water surface flow rate is adjustable via a bottom-rotation mechanism, allowing hobbyists to tailor flow to their plant species and stock load. This inflow supports both small and medium aquariums efficiently.
With a focus on keeping the surface clean, this Lily Pipe helps maintain water clarity and promotes consistent gas exchange. Its minimalist profile reduces visual distraction, and the longer stem design broadens the intake area for steadier filtration across the water column. Regular maintenance is recommended to preserve peak performance.
FZONE Glass Mini Skimmer Lily Inflow/Outflow For Mini Nano Tanks

Compact 6.5-inch mini size makes this set ideal for nano tanks. The kit includes a skimmer lily inflow and outflow, plus glass adapters and a spring brush. It supports 10mm to 13mm glass adapters to connect with various hose IDs. The borosilicate glass construction provides a clean, elegant look, while the acrylic floating section offers adjustable surface flow, ensuring efficient participation in filtration without overpowering small aquariums.
The compact design helps keep tanks aesthetically pleasing while still delivering reliable water movement. The included adapters ensure compatibility with a range of tubing choices, making this kit adaptable for small planted tanks or compact setups. Regular cleaning preserves flow and prevents buildup in tight spaces.
Buying Guide: Key Considerations For Glass Lily Pipes
- Tube compatibility: Confirm the tubing ID/OD your filter uses (common sizes include 5/8″, 17mm, 1/2″). Choose lily pipes that fit your canister filter tubing and ensure adapters are available if needed.
- Flow control: Look for adjustable bottom parts or dedicated flow regulators to tailor surface movement and overall filtration to plant density and stocking levels.
- Skimmer type: Surface skimmers help remove top-film buildup and improve gas exchange. Decide between inflow-only, inflow/outflow sets, or multi-level intake designs based on tank size and scape.
- Material build: Borosilicate glass offers clarity and durability; acrylic components provide adjustable connections and lightweight operation. Consider kits with corrosion-resistant fittings for longevity.
- Maintenance: Cleaning brushes included with some sets aid in keeping internal pathways clear. Regular maintenance ensures steady flow and reduces clogging risk.
- Aesthetic impact: Glass lily pipes are designed to be visually unobtrusive, allowing aquascapes to shine. Consider models with slim profiles and minimal external hardware for a cleaner look.
- Tank size and stock: Larger tanks with higher bio-loads may benefit from bigger inflow/outflow pipes or longer pipes for even distribution. Nano tanks may benefit from compact, adjustable mini kits.
- Installation ease: Check whether the kit requires only installation onto standard canister tubing, and verify the presence of any required mounting hardware or brackets for rimless or specialty tanks.
