High Quality Aquarium Kalkwasser Supplement (Kalk) - 32oz GFO High Capacity - Granular Ferric Oxide - 32oz (1.75 lbs.) Coral Frenzy 0.5mm LPS Pellet Food
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. CORAL FRENZY is the perfect alternative for those who do not have the time, discipline, or desire to feed live or frozen foods.
Every Ingredient is listed on the label, so there is no question of what you are feeding. There are no secret ingredients or fillers; what you see is what you get.
CORAL FRENZY is the only dry coral food on the market that has the manufactured date on the label. With a long shelf life, you are assured that it will not spoil like live or frozen foods.

Bulkhead suction screens prevent livestock and other tank inhabitants from getting sucked into the pumps and plumbing.
These fittings are threaded into standard bulkheads with threaded ends.
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.
This 250W Single Ended Mogul 14000K bulb casts a crisp-white light with a blue tint. Great for bringing out the coloration of fish and corals while providing sufficient intensity for growth. An HQI, Pulse-Start or Electronic ballast is required.
