When it comes to the growth and health of corals and other invertebrates in reef tanks, most aquarists have found the best results are acquired by dosing the aquarium with calcium, liquid vitamins and other beneficial supplements on a regular, if not daily basis. You can take the "Oops, I forgot to dose my tank", vacation concerns, and other tank maintenance worries out of performing this task by installing an automatic doser to provide a consistantly measured and timed additive dosage.
