Maintaining proper reef tank parameters is essential to the health and well-being of fish, coral, and invertebrates inside your aquarium. Fluctuations in a key aquarium parameter, such as temperature, salinity, pH, ammonia, or nitrate can result in some serious stress upon your tank inhabitants, algae blooms, and disease.

No matter what type of aquarium you keep, it is important to test and monitor critical tank parameters on a very regular basis and in order to identify changes or trends in your parameters. When it comes to reef aquariums, stability is king and you have an even wider scope of parameters that must be maintained. In addition to pH, temperature, and salinity you also need to keep a close eye on your alkalinity, calcium, and magnesium levels.

Reef Tank Water Parameters

While these parameters are widely agreed upon by hobbyists to be safe or ideal conditions for an aquarium, it is important to understand that every aquarium is different. What is right for your tank may not be exactly the same in someone else's tank. At the end of the day, the most important factor is stability within the given minimum and maximum ranges.

Before you go pouring aquarium additives or supplements into your tank, it is important to understand what you are adding and how much you need to add.
