Uneaten food and other decaying organic matter also add ammonia to the water. A natural mechanism exists that controls ammonia in the aquarium – the biological filter. It is made up of nitrifying bacteria, which live in the gravel bed. However, as with any natural process, imbalances can occur. Testing for the presence of toxic ammonia is essential, so that once detected, steps can be taken to remove it. Otherwise, ammonia in the aquarium will damage gill membranes, and prevent fish from carrying on normal respiration. High levels of ammonia quickly lead to fish death. Even trace amounts stress fish, suppressing their immune system and thereby increasing the likelihood of disease outbreaks and subsequent fish loss.\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTesting Tips:\u003c\/strong\u003e\u003cbr\u003eThis salicylate based ammonia test kit reads the total ammonia level in parts per million (ppm) which are equivalent to milligrams per Liter (mg\/L) from 0 ppm to 8.0 ppm (mg\/L), in either fresh or saltwater aquariums.

A high nitrate level indicates a build-up of fish waste and organic compounds, resulting in poor water quality and contributing to the likelihood of fish disease. Excessive nitrate also provides a nitrogen source that can stimulate algal blooms.

It works on the principle that light travels slower in media with higher RI. As a result of that optical property, light bends when it travels between two media with different RI, and beyond the critical angle, light simply reflects off the interface between the two media without refracting into the other medium. A refractometer works by passing light through a sample medium into a prism and by determining the critical angle which is unique to the particular medium. Governed by the critical angle, light exiting the prism falls only on one side of a dividing line and never on the other side. The dividing line between the two sides separates the upper blue part and the lower white part on the scale, which is designed to mark the salinity (ppt\/psu) and specific gravity (s.g.) of the medium being tested.\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003eFurther, at normal temperature range of seawater in most parts of the world, the RI and specific gravity of seawater increases at lower temperature.

In addition, many hobby grade reverse osmosis deionized water systems may not adequately remove calcium.

Testing for phosphates is standard practice for saltwater aquariums and provides valuable insight into your reef tank's 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 in your reef tank.

While doing this, it is measuring (titrating with a precision peristaltic pump) the amounts of each that are necessary to reach an expected color change (determined by the electronic colorimeter). When it finishes the titration, it sends this sample\/reagent fluid to your waste container.

But, don’t worry, we have built this feature with safety in mind. With ADC you set your target value and your starting dosing amount and ADC will only tune that dosing level +\/-35%. If it takes more than that amount of dosing to keep your aquarium at your target value, then the Apex will stop ADC, revert to your starting dosing amount, and alert you that you need to manually adjust your dosing level. Then, ADC can be re-enabled and it will continue to guide your DŌS so that it keeps you as close to your target value as possible.\u003c\/p\u003e\n\u003ch6\u003e\u003cbr\u003e\u003c\/h6\u003e\n\u003ch6\u003e\u003cbr\u003e\u003c\/h6\u003e\n\u003cp\u003eIt is possible to use ADC for all three tests – Alkalinity, Calcium, and Magnesium.

These kits include two bottles of Reagent A (changed every month), one each of Reagent B and C (changed every two months), and one bottle of our calibration seawater sample.
