How to Cycle a 24 Gallon Salt Water Tank

The nitrogen cycle is the life support system of an aquarium. The cycle is a chain of chemicals and bacteria that are responsible for keeping the aquarium free of organic waste. Without an effective cycle, the tank becomes a toxic soup of chemicals that will harm or kill the inhabitants. To get a new aquarium ready for fish, it is essential to biologically mature the filter by encouraging the growth of highly specialized bacteria in the filter system. This process is vital for the safety and welfare of all aquatic animals.The salinity refractometer , aquarium refractometer or seawater refractometer is a important tool.

How to Correct Marine Aquarium Salinity

In a marine aquarium, salinity refers to the amount of dissolved salts in parts per thousand (ppt). Specific gravity also measures salinity and expresses the density of the aquarium water compared to the density of water. The specific gravity of water is 1 and anything heavier than water has a specific gravity that is above 1. The ocean has a salinity of between 34 to 37 ppt. At 35 ppt, seawater has a specific gravity of 1.026. Aim to maintain a specific gravity of between 1.020 to 1.026 in your marine aquarium. Salinity refractomter is the useful tool.

Refractometer Gem Identification

Each type of gem has its own refraction index, a measurement calculated with a refractometer. The instrument can help you identify what kind of gem or stone you have.

How to Test Salt Water Pools

Saltwater pools are favorites as they do not require harsh chemicals to help keep the water disinfected; they simply use salt. When using a salt water pool, you must keep the salt level at a minimum of around 3500 parts per million with salinity refractometer or other tools,  according to our suggestions. To ensure that a salt water pool stays at the appropriate salt level, it is important to test the water. Most salt water pools have their own salt level readout; however, these readouts can sometimes fail, and thus it is important to have one or two backup methods available.

Water Salinity Testing

Water salinity testing is used to determine the concentration of salts dissolved in a water sample. Salinity is measured for maintenance of saltwater aquariums, to determine the suitability of water for drinking and for ecological monitoring of aquatic habitats. Salt concentration can be directly measured by evaporating a water sample and measuring the dried salts left behind (total dissolved solids, or TDS). More practical methods such as salinity refractometer Method for estimating water salinity have been developed based on the relationships between the concentration of salt ions and electrical conductivity, density and refractive index.

How to Use an Atago Refractometer

A handheld digital refractometer measures the refractive index of a solution, based on how light bends, or refracts, when traveling through the solution. This allows the user to determine the concentration of sugars, salts, proteins or minerals in a sample. One of the most common applications for a refractometer is checking sugar levels in drinks at beverage plants and breweries. The Atago refractometer can measure hot and cold samples on its prism surface. The percentage displayed on its digital readout shows the total concentration of soluble solids in the sample.

How to Mix Saltwater for an Aquarium

Saltwater aquariums require regular water changes with synthetic salt mix. Otherwise toxic chemicals and compounds can build up in the water and impact the health of your fish and plants. You also need to check the salinity of the water with the salinity refractometer before it is added to the tank. It's important to mix the water properly and thoroughly, and to use purified water. You can obtain purified water at a reduced price at your local fish store.

What Tools Could Be Used to Measure Salinity?

Salinity is the measure of how much salt is present in a sample of water. This measurement is important for many scientific purposes, but in everyday life, salinity is most commonly measured to determine the quality of drinking water and in saltwater aquariums. There are two main tools that are used to measure salinity -- hydrometers and refractometers -- and both are simple to use.

How to Measure the Salinity of a Freshwater Aquarium

The water in freshwater aquariums has almost no salt content. At times, it becomes necessary to add salt to kill bacteria or because of problems with parasites that cause aquarium fish to lose their scales -- the added salt helps the fish maintain salt in their blood during the healing process. However, as a general rule, salt should never be added to a freshwater aquarium. Freshwater aquariums with a higher than normal salt content should be adjusted through a 30 percent water change -- as opposed to the weekly 15 percent water change -- as soon as possible. A salinity refractometer can tell you exactly how much salt is present in your freshwater tank.

How to Use a Refractometer for Maple Sap

Almost everyone is familiar with the experience of putting a stick into clear water and seeing it apparently bend where it enters. That's because water affects the passage of light, refracting it as a prism would. What's more, water will refract light differently if it has another substance -- such as salt or sugar -- dissolved in it. A salinity refractometer is a device that is designed to take advantage of this to test the sugar content of substances such as maple-tree sap, making it a useful tool for maple-sugar producers.
