Coralline Algae
Coralline algae are divided into two groups: The articulated (erect), tree like with non-calcified branches  attached to the substrate; and the non-articulated (encrusting), the slow growing crusty type on the rocks which ...more>>>
Soft Corals
Soft corals can be found worldwide in tropical environments at depths of 15 - 95 feet (5 - 30 Meters). This near-surface-depth allows for currents which provide the soft corals with ...more>>>
Zooxanthellae and Corals
Zooxanthellae are the symbiotic algae that live within the hard or stony corals. The symbiotic relation is based on the corals inability to generate sufficient amounts of ...more>>>
Coral Bleaching
Coral bleaching refers to the acute release or loss of the symbiotic algae zooxanthellae from the coral tissue. The visible symptom of bleaching is the white ...more>>>
Kalkwasser in the Aquarium
The main benefit of Kalkwasser use is that it replenishes calcium in the reef and marine tank. Even the most inexperienced hobbyist can easily make Kalkwasser. Kalkwasser is extremely beneficial ...more>>>
Converting a Freshwater Aquarium to Saltwater
A common misconception is that you have to graduate from freshwater to saltwater. This is of course not true, as a freshwater species aquarium can be as challenging as a reef set-up, or as easy ...more>>>
 Saltwater Salinity and Specific Gravity
The preferred water for marine and reef tanks is RO/DI water, as it is in a very pure form. The commercial salt mix contains all the salts and minerals needed. Salinity describes the content of these dissolved salts and minerals in the water and is measured in parts per thousand (ppt) ...more>>>
Live Rock
Most live rock comes from areas close to natural reef habitats. It basically consists of dead and washed away coral, overgrown with a multitude of organisms. Highly porous with a larger surface than most filters can ...more>>>
UV Sterilization
Ultraviolet (UV) sterilization is a process to eliminate biological contamination, namely parasite fungus and bacteria. Two types are commercially available, both in tube size. Generally the one containing a wet bulb -at which the water passes directly past the UV bulb- is cheaper. The other type available has a protective quartz tube around the bulb (dry bulb) ...more>>>
Reverse Osmosis (RO)
In order to understand the method of osmosis; imagine a container with a semi-permeable divider. One half contains tap water and the other half distilled water. Nature's way for maintaining cellular fluid levels triggers a natural action in equalizing both fluids ...more>>>
Mini Marine Basics
Have you ever wondered why there aren't more hobbyists in this hobby? It is probably because of the horror stories that have been told to them by friends, relatives, even pet stores about the immense amount of money, time, and equipment they will need ...more>>>
Algone and Reefs
Corals and invertebrates come from environments that are extremely low in nitrates. Accumulating nitrates will affect the appearance and liveliness at levels that may not effect fish, or affect them at a lesser degree.
High nitrate levels in reef tanks indicate low water quality. High nitrate formation increases the chances for ...more>>> |
