Frequently Asked Questions

Q: What makes quartz ball filter media effective at removing yellow water in aquariums?

A: Quartz ball filter media features a hollow, porous structure that maximises surface area for both mechanical and biological filtration. This design traps tannins and organic compounds that cause yellow discolouration, while also hosting beneficial bacteria colonies that break down harmful ammonia and nitrites — resulting in clearer, healthier water over time.

Q: How often should I clean or replace the quartz ball aquarium filter media?

A: We recommend rinsing the quartz balls every 2–4 weeks during your regular aquarium maintenance. Always rinse them in used tank water — never tap water — to preserve the beneficial bacteria living on the media surface. Unlike disposable sponge pads, quartz ball media can be reused indefinitely with proper care, only needing replacement if they visibly deteriorate or crack.

Q: Is this quartz ball filter media safe for shrimp, corals, and sensitive fish species?

A: Yes. These quartz ball filter media pills are free from high-concern chemicals and are made from inert, non-toxic quartz material. They will not leach harmful substances into your water, making them safe for sensitive inhabitants including dwarf shrimp, corals, and delicate tropical fish species.

Q: Can I use these quartz balls in a pond or outdoor water feature?

A: Absolutely. These filter balls are suitable for garden ponds, koi ponds, and outdoor water features. Simply place them in your pond's filter box or a mesh filter bag inside the pump housing for effective mechanical and biological water purification all season long.
