KH Alkalinity - Carbonate Hardness Water AnalysisAlkalinity is essentially a means of quantifying the stability of pH in a solution, such as aquarium water. It is a measure of the concentration of...

The pH-value or acid value indicates how acidic or alkaline water is. It is a measure of the concentration of the acidic or alkaline components in a hydrous solution. Pure water will react neutral...

Mg Magnesium Water Analysis for AquariumMagnesium is a major salt in natural seawater. Contrary to its significance this element was ignored for a long time. We know today that Magnesium creates a...

Lab Quality Calcium (Ca) Water Analysis for the Marine Hobbyist Calcium is the primary building block for corals, calms, calcareous algae and many other marine organisms that we grow in our aquarium...

It is well known that, in an aquarium populated by corals, it is important to avoid the need of medicine treatment and increase in PO4 as well as NO3 levels. Where SPS are also present, it become...

Biological filtration is a method that uses naturally occurring nitrifying bacteria to detoxify nitrogenous wastes. One type of bacteria (Nitrosomonas spp.) converts ammonia to nitrite while another...

The ELOS Copper Test Kit combines ease-of-use, with laboratory-grade precision. It can be used to detect copper or to measure residual copper levels before and after using copper cures in fish-only...

Phosphate Water Analysis for Fresh Water or Marine AquariumsPhosphate build up in the tank appears to be a fairly common problem in fresh water and in marine aquariums. They are present in most tap...

Biological filtration is a method that uses naturally occurring nitrifying bacteria to detoxify nitrogenous wastes. One type of bacteria (Nitrosomonas spp.) converts ammonia to nitrite while another...

Ammonia (NH3) is toxic to corals, invertebrate and fishes. At high pH level (as in a marine aquarium) and at increased temperatures, NH3 can kill the aquarium inhabitants. In freshwater aquaria its...
