How much media do I need for my tank?

The stated dose is 100 g per 100 litres of water, so a 1 kg bag treats about 1,000 litres. Larger systems need multiple bags.

Does it work in a marine tank?

Yes. It is listed as suitable for marine aquariums as well as African Rift Lake cichlid setups.

Will it change my pH?

The yellow spheres are described as neutralising and stabilising pH, and the media is called a natural pH buffer. Expect a buffering effect rather than a large shift.

Do I need to rinse it first?

Yes. Wash the spheres before use, then bag them and place them in the filter.

Can I mix it with ceramic rings or other bio-media?

Yes. It works alongside existing biological media; the mineral and buffering functions are what set it apart from plain ceramic.

How often should I replace it?

The material does not state a replacement interval. Mineral release and buffering fade with use, so watch pH and mineral levels and refresh when they drift.

Our take on the NANO Natural Bio Smart Sphere Media 1kg

A 1 kg bag of mineral-infused filter spheres for freshwater and marine aquariums, sold with a mesh filter bag. Each color carries a different compound: yellow buffers pH, black absorbs heavy metals, pink adds trace elements, neutral feeds nitrifying bacteria and blue is an active anion aimed at fish immunity. The pitch is surface area and mineral release in one, with two spheres claimed to match 30 ceramic rings. It suits keepers who want pH buffering and trace minerals alongside biological filtration, especially African Rift Lake cichlid and marine setups; plain sintered ceramic or plastic bio-media offers more raw surface per volume but no buffering or mineral release.
