Kalkwasser (lime water in German) is an age old method of maintaining calcium and alkalinity dating back to the development of the Berlin Method of reef keeping. Kalkwasser is essentially a Calcium Hydroxide solution. It works by capturing free Carbon Dioxide in your tank water and converting it into Bicarbonate ions. This has a beneficial effect on your reef. Kalkwasser raises the calcium, alkalinity, and pH as it is slowly dripped in.
Granular Ferric Oxide (GFO) is a chemical filter media that inhibits algae growth in reef aquariums by removing phosphate from the water column. There are two types of GFO that Advanced Reef Aquarium carries, a standard absorption variety and a special high capacity variety that roughly has twice the absorption power.
A CPR Aquatics Flow Eductor increases flow and circulation in the reef aquarium. This unit has a 3/4" male pipe thread adapter.
An eductor can increase flow by up to 4x the original flow coming from the pump. They are able to accomplish this by sending a jet of water through a specially designed funnel. As the water passes through the funnel, it suctions additional water through it thus multiplying the overall amount of water being moved.

Coral Rx is a great preventative protocol for dipping newly acquired corals, treating infected colonies, and quarantining coral. An ounce of prevention is worth a ton of coral in this hobby. Many of the headaches caused by malevolent pests can be managed up front by dipping your corals. The first time we used it, we immediately saw inverts jumping off of the corals and quickly perishing.
The German-made Radium 20,000K bulb is a legend in the reefkeeping hobby. You will not have to look very hard to find a legion of reef aquarists that swear by this bulb. For decades this bulb illuminated some of the most incredible show tanks in the world. This metal halide bulb is the perfect blend of intensity and aesthetics with a long track record of promoting coral growth and color.
