Frequently Asked Questions

Q: How many quartz aquarium filter media pieces are included in one order?

A: Each order includes 10 individual quartz nano filter media pieces. Each piece measures 9.6 × 2.4 × 2.4 cm and features 8 slots designed to maximize biological filtration surface area in your fish tank or pond.

Q: Are these quartz filter media suitable for both freshwater and saltwater aquariums?

A: Yes! The inert quartz material does not leach chemicals or alter water parameters, making these biochemical filter media safe and effective for both freshwater and saltwater (marine) aquarium setups, as well as outdoor ponds.

Q: How do I maintain and clean these nano filter media?

A: To clean, gently rinse the filter media in a bucket of used aquarium water or dechlorinated tap water during your regular water change. Avoid rinsing under hot or chlorinated tap water directly, as this can reduce the beneficial bacteria colonies that have established on the media surfaces. These pieces are reusable and built to last with proper care.

Q: What types of filtration systems are compatible with these quartz filter blocks?

A: These compact nano filter media are compatible with a wide range of filtration systems, including canister filters, hang-on-back (HOB) filters, internal box filters, sump chambers, and outdoor pond filter units. Their standard rectangular nano size fits most filter media compartments.
