Evaluating Aquarium Water with NT Labs: A Consumer's Handbook

In the vibrant world of community aquariums, maintaining a balanced environment is crucial for the health and well-being of aquatic species. One of the key challenges faced by aquarists is managing ammonia spikes, which can have detrimental effects on fish and other inhabitants.

Ammonia, a byproduct of fish waste, uneaten food, and decomposing organic matter, is converted into less harmful forms through a process known as the nitrogen cycle. However, fluctuations in the nitrogen cycle can lead to an accumulation of ammonia, causing spikes that are harmful to aquarium inhabitants.

Ammonia spikes are often the result of overfeeding, overcrowding, sudden changes in the beneficial bacteria population, the introduction of new fish or organic matter without proper cycling or bacterial seeding, and elevated pH levels above 8.5 [1][3]. In a mature aquarium with a well-established filter, beneficial bacteria should be able to convert ammonia quickly, preventing spikes even if fish numbers double or triple. However, disruptions to the bacterial colony can cause sudden ammonia increases [2].

The effects of ammonia spikes are harmful to aquarium inhabitants. Ammonia can cause damage to fish gills, leading to burning and respiratory distress. It can also elevate stress levels, weaken immune systems, and lead to organ and brain damage from prolonged exposure to toxic ammonia levels. In severe cases, it can increase the risk of death [1].

To prevent ammonia spikes, it is essential to maintain stable conditions, avoid overfeeding, perform regular but careful filter maintenance, and use bacterial supplements when cycling or after disruptions. Adjusting water pH to below 8.5 can also reduce ammonia toxicity and improve bacteria efficiency [1][3][4].

In addition to managing ammonia levels, it's important to consider the pH, KH, and GH values in your aquarium. pH, the measure of how acid or alkaline a substance is, should ideally be around 7.0 for most freshwater aquarium conditions. KH, the measure of carbonates and bicarbonates present in the water, acts as a pH stabilizer, with a value of 6 dKH being ideal for optimal buffering capacity [5]. GH, the measurement of calcium and magnesium in the water, should be around 8 dGH for optimal mineral levels [5].

For community aquariums, maintaining a pH between 6.5 and 8.5 is generally suitable for most fish species. However, some species, such as African cichlids from the Great Rift Lakes, tend towards higher pHs, while acidophilic species from South America or Asia, like Apistogramma, discus, and gouramis, prefer a lower pH between 5.0 and 6.5 [5].

Regular water changes dilute nitrate levels back to recommended levels, and where possible, it's best to try to match the GH to the requirements of your specific fish species [6]. In areas of low oxygenation, such as within the substrate or gravel of the aquarium, denitrification completes one path of the nitrogen cycle [7].

It's important to note that nitrate cannot be consumed by typical filter bacteria and levels rise over time. While nitrate is not particularly harmful to aquatic species, some may show signs of toxicity when nitrate concentration exceeds 80-100 mg/l [8].

In conclusion, managing ammonia spikes and maintaining optimal pH, KH, and GH levels are crucial for the health and well-being of aquarium inhabitants. By understanding the factors that contribute to ammonia spikes and taking proactive measures to prevent them, aquarists can create and maintain a thriving community aquarium.
