The Twinstar Nano steriliser inhibits green algae effectively without a harmful influence on the aquarium’s ecological environment, keeping it clean by eliminating spores from the initial propagation. It has no harmful effect on plants, fish and aerobic bacteria as it does not generate any toxic substance.Why do plants grow healthy and faster with the Twinstar Nano? Nitrogen, phosphorus and potassium are fully provided from the soil in new setups, but the microelements rapidly begin to deplete. To grow plants quickly and healthily in an aquarium, all nutrients should be provided in the right proportions. The steriliser increases insufficient microelements and promotes the rapid plant growth by removing blocked lights by algae.
