Glass Lily Pipes

Glass lily pipes are the signature accessory of a refined aquascape. These hand-blown borosilicate glass inlet and outlet pipes replace the standard plastic tubing that comes with canister filters, transforming functional plumbing into an elegant design element. Named after the flared, lily-flower shape of the outflow, they provide superior water distribution while being nearly invisible in the tank.

Components

Outflow (Lily Pipe)

The outflow pipe features a wide, flared opening that disperses the return water in a broad, gentle sheet across the water surface. This creates:

• Even water circulation throughout the tank.
• Gentle surface agitation for gas exchange without harsh currents.
• A visually pleasing, cascading water flow.

Inflow (Intake Pipe)

The intake pipe draws water from the lower portion of the tank. It typically features:

• Slotted Design: Vertical slits that prevent fish and shrimp from being sucked in.
• Surface Skimmer Variant: Some inlets have a floating head that skims the water surface to remove protein film.

Why Glass?

• Transparency: Glass is nearly invisible in water, unlike opaque green or grey plastic.
• Biofilm Resistant: Smoother surface than plastic, reducing algae growth.
• Heat Resistant: Borosilicate glass handles temperature fluctuations without warping.
• Aesthetic: Transforms utilitarian plumbing into a design feature.

Sizing Guide

| Hose Size | Tank Size | Typical Use | |---|---|---| | 12/16mm (13mm) | Up to 100L | Nano to mid-size tanks | | 16/22mm (17mm) | 100L+ | Medium to large tanks |

Ensure your lily pipes match the hose diameter of your canister filter.

Cleaning & Maintenance

Glass lily pipes require regular cleaning to prevent algae and biofilm buildup:

1. Weekly: Wipe the exterior with an algae pad.
2. Monthly: Soak in a diluted bleach solution (1:20) or hydrogen peroxide for 30 minutes, then rinse thoroughly.
3. Alternative: Use a flexible pipe cleaning brush for the interior curves.
4. Caution: Handle with care — glass pipes are fragile and can chip or crack if knocked.
