Dispensing aids can make the maintenance of a planted tank or an aquascape considerably easier. Manual dispensing aids are e.g. dosage pumps or measuring cups that can both be screwed onto the fertiliser bottle.
Besides the manual aids, there are also automatic dispensing aids like e.g. dosage pumps with one or several channels. An automated dosage pump can add different aquatic plant fertilisers to your planted tank or aquascape in a comfortable way, controlled by a clock timer. When you have this kind of dosage pump running on your tank you can go on holidays without preoccupation, as it will keep adding the fertiliser to your tank reliably and precisely even though you are away from home.
