Neutro T Aquarium Plant Fertiliser

Neutro T is a daily liquid fertiliser formulated for low-tech planted aquariums — those not using pressurised CO₂. It provides all the trace elements your plants need, including iron, in a stable form that’s absorbed quickly and consistently.

Why plants need daily fertiliser

Tap water contains no usable plant nutrients. Without regular fertilisation, even low-maintenance species like Java fern and Anubias will slowly lose colour, stall in growth, and become susceptible to algae. Neutro T provides a steady daily supply — dosed in small amounts so nutrients never drop between doses.

What’s in it

All essential trace elements: iron, potassium, manganese, copper, boron, zinc, and molybdenum. Neutro T does not contain nitrate or phosphate, so it won’t directly fuel algae — it just gives your plants what they need to stay healthy and competitive.

How to dose

Add 5ml per 100L every day. Daily dosing matters — adding a week’s worth in one go is less effective and can cause imbalances. Any time of day is fine, as long as it’s consistent. The bottle cap measures 10ml, or use our dispensing bottle for easier daily doses.

Which fertiliser do I need?

Neutro T is for low-tech tanks without pressurised CO₂. If you’re injecting CO₂, use Neutro+ instead — it adds macronutrients (NPK) that high-demand plants need at higher growth rates. If you’re not sure which you have, you’re almost certainly low-tech.

We also recommend pairing Neutro T with Neutro CO₂ (liquid carbon) regardless of setup — it provides an additional carbon source and helps suppress algae. The Neutro Combo Low Tech bundles both together at a saving.

Available in: 500ml · 1000ml · 2000ml · 4000ml. Shake well before use.
