Expanding an aquarium garden can result in an impressive green paradise, both below and above the water surface.
But the more plants you add, the more water your system will require.
Large-leafed plants such as Monstera and Pothos in particular use considerably more water due to their size and the associated evaporation. This requires that fresh water be added more frequently to keep the water level in the aquarium constant.
The positive effect of fresh water 
Regularly adding fresh water has numerous benefits for your aquarium and its inhabitants:
1. Improved water quality: By frequently topping up the aquarium with fresh water, the water quality is improved. Old water is diluted, which leads to a reduction in pollutants and waste materials that accumulate over time.
2. Healthy plants: Aquarium plants benefit greatly from fresh water. The nutrients in the new water promote plant growth and ensure strong and healthy plants. This is especially true for highly demanding plants such as Monstera and Pothos.
3. Well-being of the fish: Fish and other aquarium inhabitants feel more comfortable in fresh water. The increased oxygen content and improved water quality contribute to better health and vitality of the animals.
4. More stable water parameters: Regularly topping up with fresh water helps keep water parameters stable. Fluctuations in pH, hardness and temperature are minimized, creating a more stable and safer environment for all aquarium inhabitants.
No substitute for regular water changes
It is important to emphasize that adding fresh water does not replace regular water changes. Water changes are essential to completely remove organic waste and pollutants that accumulate over time. Regular water changes should therefore remain an integral part of aquarium care.
Conclusion
Expanding your aquarium garden with large-leafed plants such as Monstera and Money Plant can increase water requirements. This will result in more frequent fresh water additions, which in turn will have numerous benefits for water quality, plants and animals in the aquarium. However, water additions should not be seen as a replacement for regular water changes. A combination of frequent fresh water access and regular water changes will ensure a healthy and thriving aquarium system.
