Maintaining your freshwater aquarium simply

A clean and well-balanced freshwater aquarium does not require complicated maintenance, but it does require regularity. With a few simple actions spread throughout the month, it is possible to maintain healthy water, fish in good health, and an aquarium that is pleasant to observe.

This maintenance routine is suitable for both beginners in fishkeeping and more experienced aquarists.

On the 1st of the month: general maintenance of the freshwater aquarium

This monthly maintenance helps limit the accumulation of waste and preserve water quality.

Water change (20 to 30% of the volume)

Water changes are essential in a freshwater aquarium. They help remove nitrates and pollutants naturally produced by fish and plants. Replace approximately 20 to 30% of the volume with water suited to the needs of your livestock.

Surface cleaning of sand or gravel

Using a gravel vacuum, remove visible waste from the surface of the substrate (uneaten food, waste). There is no need to clean deeply: the substrate houses bacteria that are beneficial to biological balance.

Cleaning the glass

If algae appear, clean only the necessary areas to maintain good visibility, without trying to remove every trace of algae.

Plant trimming (if necessary)

Remove damaged leaves and trim plants that are growing too densely. Regular trimming promotes healthy growth and a more harmonious aquarium.

• the filter (by carefully cleaning the rotor)

• the heater

• the lighting

Clean, well-functioning equipment ensures stable water and healthy fish

During the month: compensating for evaporation

In a freshwater aquarium, evaporation is normal. If the water level drops, simply add water to compensate, without performing a full water change.

You can also clean algae from the glass if needed.
