Why would you need such a thing? Can’t you just take the bottles and add a few drops of solution to your tank when it needs it?

The ecosystem in your tank uses up the beneficial bacteria, vitamins, fertilizers, trace elements and minerals and unless replaced, can become depleted enough to harm your living inhabitants. The dosing system automates the process by offering to add, drop by drop, the needed supplements. Most units are controlled on the doser by adjusting the amount you need to dose. Some have 2 outputs, some more. GHL offers two units. One stands alone and includes all the controlling built-in. The second unit is made to connect to the Profilux series of controllers.

Eheim offers a battery powered unit that sits on your hood to drip the fluids into the tank water. Very simple and effective.
