Well cared for aquatic plants in the aquarium continuously release oxygen into the water and thus contribute to the purity and survival of the plant and animal inhabitants. In this article you will find out what is important when it comes to care.

Changing the water is one of the regular maintenance measures in the aquarium

The most important care measures for aquatic plants in the aquarium

The following points should be observed when caring for aquatic plants in the aquarium:

  • substrate
  • water
  • water change
  • fertilization
  • light
  • To cut

substrate

Do not make the substrate too fine-grained so that the roots of the aquatic plants can be adequately supplied with nutrients and good ventilation is also ensured. Otherwise, the roots will die and rot.

Recommendation: A grit between three and eight millimeters is perfect.

The sensible layer structure at a glance:

  • Substrate long-term fertilizer (one to two centimeters)
  • Aquarium gravel (lighter is more suitable, darker robs a lot of light)

water

Use water that is as soft as possible. Many plants only cope moderately with hard water.

water change

Change the water once a week to add fresh nutrients to the aquarium.

fertilization

Check regularly with an iron test whether your aquatic plants are sufficiently supplied. In principle, too little fertilizer is just as harmful as too much fertilizer.

There are various fertilizers to choose from in specialist shops, such as liquid fertilizer or CO2 fertilizer with gas. However, beginners should avoid the latter because it requires a good understanding of chemical relationships.

Recommendation: For a smaller aquarium (up to 80 centimetres) you can use an easy-to-use Bio CO2 set.

light

Aquatic plants in the aquarium need light for photosynthesis. However, you should avoid direct sunlight. Indirect sunlight and/or artificial light sources with a suitable spectrum are more suitable.

Note: Replace the fluorescent tubes after a year at the latest, as the luminosity decreases significantly over time.

To cut

Shorten fast-growing aquatic plants regularly and remove dead plant parts from the aquarium.

Recommendation: You can replant the severed ends and grow new aquatic plants straight away.

General information on the thriving of aquatic plants in the aquarium

Even under the best conditions, aquatic plants in the aquarium need time to thrive. After a new planting, it takes about four to five weeks for the biological balance to be established. Once this is the case, the small water world is largely stable, so that apart from cleaning the water regularly, you hardly have to intervene.
