Automatic Dosers - Top Picks
Most reef tank aquarists have found that they get the best results from their corals & inverts if they dose their tanks daily with kalkwasser (lime water) and supplements on a daily basis. Automatic dosers not only take "Oops, I forgot to dose the tank yesterday" and vacations worries out of daily dosing, but they also produce a consistent dosing, day after day.
