The only limit is what you can imagine.
The practice of creating realistic nature aquariums is known as aquascaping. Not only does aquascaping utilize nature and artistic composition but also science, biology, and water chemistry. This profound relationship between nature, artistic design, and science mesh to form beautiful aquatic landscapes perfect for any home.
Aquarium science greatly evolved in the past few decades. It started by an eager pioneer researcher and paleobiologist Walter Adey who built the first research tank in late 1970. His goal was to build a tank that would make it possible to monitor and experiment on a coral reef ecosystem in the laboratory.
Experimental tanks today offer
immeasurable value to the scientific community, especially as researchers and environmentalists
work to save coral in the wild by breeding it in captivity.
Coral reef Awareness is more-than-ever important today because it serves as a call to action for consumers, businesses and organizations to reflect on the delicate ecosystem of our ocean’s coral reefs.

Two main categories are:
– Freshwater aquariums
– Saltwater aquariums
– Saltwater aquariums
which often become imitations of ocean environments.

The more artistic types of aquariums use natural elements to create an aquatic landscape. In the absence of artificial decorations, these natural aquariums look to our environment as a source of inspiration. Whether it’s an underwater Amazon jungle, Japanese-style “Iwagumi” rock formations or a tropical coral reef, owning a living work of art in your home has never been easier and more exciting!
Water quality is very important in aquaristics as poor water quality can effect the health and growth of the fish. It is important that farmers pay attention to the water’s chemical and physical factors.

pH is a measure of the hydrogen ion concentration in your water; the higher the concentration, the more acidic the water is. A neutral pH is 7; most fish can live in a general range between 6 and 8. Keeping the pH stable and in optimal ranges reduces stress on your fish and aquatic animals, helping them resist disease and tolerate other stressors. Maintaining an ideal pH can also dramatically improve growth, behavior, and overall appearance.

Alkalinity is measured in degrees of carbonate hardness, commonly abbreviated as dKH. Critical to marine environments, alkalinity not only provides the carbonate ion required for calcium carbonate skeletal regeneration of coral reefs, but it also acts as a pH buffer against large changes in acidity. Designed as a more accurate alternative to chemical test kits, the HI772 provides quick, accurate results in a few easy steps.
Alkalinity
Whether you are maintaining your main reef tank or trying to give your frag tank the proper calcium dosage, our Marine Line of Checkers makes testing your tank levels so much easier.


Required for the development of calcium carbonate skeletons of coral reefs, calcium is a crucial component of marine waters.
Calcium


Nitrate is a by-product of the Nitrogen cycle. Excessive amounts of nitrates promote the growth of undesirable organisms including algae and dinoflagellates while insufficient amounts can lead to starvation in which SPS and other corals will show signs including the loss of color and paleness.
Nitrate

Nitrification is the biological oxidation of ammonia (ammonium ion) into nitrite followed by the oxidation of the nitrites to nitrates. The first step of this 2-step process is carried out by nitrifying bacteria. During this quick process, the ammonium levels drop while the nitrite levels increase. Since nitrite is just as harmful as ammonia, nitrite levels should be maintained at immeasurable levels. A mature biological filter should be able to keep nitrite levels low.
Nitrite


Testing for phosphates is standard practice for saltwater environment and provides valuable insight into your water chemistry to help ensure long-term coral health. Phosphates are one of the many forms of phosphorus compounds found in marine waters. Excessive phosphate levels can prevent calcification, skeletal formation, and growth of many coral species, particularly those referred to as SPS or small-polyp stony. In addition, high phosphate levels can cause nuisance algae growth. This can become problematic because algae often outcompetes sessile organisms for light, nutrients, and space, jeopardizing long term balance & health.

Ammonia
Ammonia is naturally found as part of the nitrogen cycle of a tank as aquarium organisms produce it as waste. In a balanced tank, the majority of ammonia is consumed by bacteria and the nitrogen cycle continues. When out of balance, ammonia toxicity can wreak havoc on tank inhabitants. It is important to monitor ammonia levels to ensure they remain steady and low.

Monitoring the salinity of artificial seawater is crucial so as not to create saltwater with an improper salinity level, as it could stress marine life.
