The most important benefit of a floor heating system is the integration of the substrate into the aquarium's temperature range. In contrast to a bar heater it enables an even temperature in the water and the substrate. That is exactly the situation in a natural habitat. Additionally, the groundwater flow in natural waters is imitated, the plants are provided with nutrients for better growth and the decomposition of organic waste through bacteria is significantly boosted by improved water circulation. This creates naturally produced conditions for an ideal aquarium.
