This high quality plant food provides your aquarium plants with essential elements:

Feeding your plants properly helps to reduce the growth of algae in the aquarium.

Of course, we do also recommend the correct lighting and water parameters along with a suitable plant substrate for best plant care. If you need any aquarium care advice, feel free to book in with one of our aquarists for an Aquarium Health Check.

Ferropol 250ml – usage and dosing

On the first dose add 10ml per 40 litres of aquarium water. After that, add 10ml per 80 litres weekly.

The bottle is supplied with a dosage lid so that you can easily measure how much Ferropol to add.

This product is only suitable for freshwater use.

An environmentally friendly refill bag is available when you need a top up.

Top Tips:

As we mentioned earlier, excellent plant health also requires other aquarium conditions.

Make sure that you have a good quality aquarium light that isn’t too old. Metal halide or T5 and T8 bulbs are best changed at least once a year to maintain the correct spectrum for plants to thrive. Most LED lights will last for many years. If you have old lighting, why not think about moving on to LEDs? They will save you money in electricity and in bulb changes.

As well as providing a high quality liquid food for your plants, also think about rood feeders. If it is a new set up you could start off with a substrate specifically designed for plants like JBL Manado. If you have a well matured substrate, you can top up nutrients with root balls.

CO2 will also help your plants to flourish.
