Hisin Airstone Disk 20 cm

Description

Large Disc for High Output Aeration

The Hisin Airstone Disk 20 cm is a premium large-diameter disc air stone designed to deliver broad, fine bubbles for superior oxygenation in aquatic environments. Crafted with a ceramic face and fortified with a black plastic surround, this disc is built to last and maintain performance even in demanding setups.

Key Features

• Large surface area (20 cm / 8″): Covers more space with fine bubbles, promoting even oxygen distribution and surface agitation.
• Ceramic diffusion material: Produces micro-fine bubbles that dissolve oxygen more efficiently vs coarser stones.
• Protective plastic bezel: A black plastic surround helps protect the edges and prolongs lifespan by reducing chipping or damage.
• Durable & safe material: Safe for freshwater, ponds, maybe saltwater (confirm with brand), built to resist erosion and clogging.

Typical Applications

• Large aquariums needing enhanced oxygenation or strong bubble effects
• Ponds or water features where surface agitation is useful for water quality
• Paludariums, ripariums where you want fine mist / aeration zones
• Quarantine or holding systems with heavy bioload requiring strong oxygen diffusion

Technical & Usage Notes

• Air pump compatibility: Use with an air pump that can supply enough volume to push air through a disc this size. Pressure drop may be higher vs smaller stones.
• Tubing size: Fit with standard airline hose (confirm the compatible diameter). Ensure connection is tight to prevent air leaks.
• Placement: Place disc on flat base or weighted surface so it doesn’t float or shift. Allow clearance so bubbles can rise freely.
• Cleaning: Clean periodically (rinse or soak) to remove biofilm/mineral buildup; avoid harsh chemicals; ensure fully dry or thoroughly rinsed before reuse.
• Safety & longevity: Avoid exposing to direct intense physical impacts; the ceramic face may crack if dropped or struck. Also ensure plastic surround is intact to protect edges.
