Distinguish between the Dennerle or Söchting dispenser and the matching refill. Compare aquarium volume, dosing period, fertiliser compatibility and included components.
Choose an automatic fertiliser dispenser for the aquarium
Automatic aquarium fertiliser dispensers release plant nutrients gradually without daily manual dosing. The current range includes the Dennerle Dosator, the Söchting Dosator and the matching Söchting special fertiliser. A refill or fertiliser product is not the same as a complete dispenser.
Choose the system according to aquarium volume, plant requirements, the fertiliser used and the desired dosing period. Check the stated capacity and whether the product is a complete device, replacement filling or accessory. The systems operate without conventional electronic dosing pumps and must be installed and filled exactly as specified.
Automatic dosing does not remove the need to monitor plant growth and water parameters. Begin with an appropriate dosage, observe the aquarium and adjust only according to the product instructions and actual nutrient demand. Avoid combining several fertilisation systems without considering their total nutrient input.
