Tropical Ferro-Aktiv Iron Fertiliser for Aquatic Plants 30ml

Tropical Ferro-Aktiv 30ml is a liquid iron supplement designed for planted aquariums. Iron is a core building block of chlorophyll — the pigment responsible for healthy green colouration in aquatic plants — and without consistent replenishment, most planted tanks will show signs of deficiency over time. This is a straightforward, targeted solution for keepers who want their aquatic planting to thrive rather than just survive.

Why Iron Matters

Iron deficiency in aquatic plants typically shows as chlorosis: leaves lose their green colour, turning pale or yellowish while growth slows or stalls. Ferro-Aktiv addresses this directly by providing a reliable source of ferric iron, keeping chlorophyll production on track and supporting strong, visible plant health.

How to Use

Dose at 10 ml per 100 litres of water. Apply at least once a week, ideally during water changes to maintain consistent iron levels. In heavily planted aquariums with higher demand, smaller doses applied more frequently will deliver better results than a single weekly addition.

Pack Size

• This listing is for the 30 ml bottle
• Also available in 500 ml for larger or more heavily planted systems

Regular use of Tropical Ferro-Aktiv keeps aquatic plants in genuinely good condition — vibrant colour, steady growth, and none of the telltale signs of iron-starved leaves.
