Aquarium size and make-up materials

Types of aquarium water systems

7 Important parameters to watch over in aquariums

1. High water quality: high water quality is the primary requirement for maintaining aquatic systems in aquariums. Chemical methods, biological filtration, and replicating the natural system are the primary means of sustaining water quality. To maintain the health of aquatic organisms, aquarists may also need to consider water clarity and dissolved wastes;
2. Water temperature: aquatic organisms only have optimum growth under specific water temperature. Check and maintain the optimum temperature for the species reared;
3. Water pH: depending on the cultured species, a favourable pH range (often alkaline) has to be maintained. Aquarium enthusiasts are particularly interested in matching water quality to a fish’s known tolerances to create an optimal habitat for expensive marine fish species. In the aquarium as in the natural ocean, adding a buffer such as oyster shells can raise alkalinity. The concentration of calcium carbonate can be used to calculate the alkalinity of the aquarium water;
4. Tank décor: décor doesn't only catch the eyes of visitors, but often has biological significance in an aquarium. e.g. décor stones and hollow materials will act as reproduction site and shelter;
5. Dissolved oxygen level: waste materials cause the aquarium water to become rich in dissolved nutrients. The ensuing environment favours plant life (algae) and culminates in low levels of dissolved oxygen that stress aquarium animals. Thus, oxygen levels have to be checked constantly especially in closed water systems - use an air pump to increase oxygen supply if noticed to be low;
6. Salinity: some fish species only live in freshwater, some thrive in salt water, and some have adapted to live in either fresh or salt environments. Stenohaline fish, which are found usually in either fresh or salt water, can survive only in a restricted range of salinities, while euryhaline fish, which may inhabit estuaries, tolerate a wide range of salinities;
7.  Finally, watch over reflections and acoustics: a lot of noise and light may stress up some species hence negatively affect their growth;
