Care

It is often difficult to precisely mimic a fish’s natural surrounding but we should try to make the aquarium as close to nature as possible to avoid the fish becoming ill.

The aquarium system works best when the water, plant life, equipment and fish are all in harmony with one another. We have developed water care products that help to remove all harmful substances from tap water whilst adding essential nutrients and bacteria to make the aquarium a healthy, balanced environment for your fish – as close to nature as possible.
