Aquaforest AF Remineralizer 250ml
A liquid freshwater aquarium mineral supplement designed to remineralise reverse osmosis, deionised and distilled water before it is added to the aquarium. Ideal for aquarists using purified water, planted aquariums and freshwater community setups, this easy-to-use formula restores essential minerals that fish, plants and beneficial biological processes need for long-term stability.
Purified water is useful for controlling aquarium water quality, but on its own it lacks the minerals required to support healthy fish, strong plant growth and stable water chemistry. Aquaforest AF Remineralizer enriches water with important minerals, including easily absorbed calcium and magnesium, while helping raise general hardness and carbonate hardness.

I’ve been using this for my planted tank for three months now. My plants are growing stronger and the water stability has improved. The instructions are clear and it’s easy to use. No fish issues so far.

Works well with my RO water. My shrimp and bettas seem more active. I notice the plants have better root development. A small bottle, but lasts a long time for my 100-litre tank.

Great product for maintaining water balance. I mix it once a week and my tank has been stable without frequent water changes. My aquarium plants look vibrant and healthy.
