The dosing cup, which supplies the aquarium with a maximum of 20 ml per filling, allows fertilizer to be dosed precisely and quickly. The fertilizer bottle can only be stored horizontally with the red lid screwed on. With the dosing cup screwed on, please always store the fertilizer bottle in an upright or vertical position, otherwise the fertilizer can run out.
The dosing cup has a 28 mm thread and is suitable for the Aqua Rebell range of fertilisers. The riser pipe has to be shortened for use within the Aqua Rebell 500ml bottles.
