About This

• Enhanced Mechanical Filtration for Crystal Clear Water: Natural quartz balls effectively trap fish waste, uneaten food, and suspended particles to reduce cloudy water. Ideal as mechanical filter media for canister filters, sumps, and HOB systems, improves water clarity without altering chemistry
• Inert Quartz for Stable pH and Hardness: Made from high-purity quartz material that maintains consistent water parameters; will not leach or alter pH/GH. Safe for freshwater, saltwater, reef tanks, and planted aquariums
• Open-Pore Structure Boosts Water Flow and Oxygen Exchange: The porous surface design prevents channeling, enhances water circulation inside your filter, and maximizes oxygen exchange. Reduces dead zones for long-term filtration support
• Traps Debris and Controls Odor Naturally: Rough-textured quartz balls capture fish debris, minimizing ammonia sources and unpleasant smells. Helps control odor without chemicals or carbon – keeps tank water fresh while reducing filter maintenance frequency
• Generous 30 oz with 4 Reusable Mesh Bags: Includes 30 oz of quartz filter balls + 4 filter bags. Loose media format fits all filter types: canister, sump, top, hang-on-back (HOB), pond, and DIY systems. Perfect replacement for ceramic rings or bio balls
