Keeping the pH in a suitable range (5.0-9.0 for freshwater systems) is crucial to maintain the health of both the fish and biofilter. pH is typically controlled by the addition of alkalinity in the form of lime (CaCO 3) or sodium hydroxide (NaOH). A low pH will lead to high levels of dissolved carbon dioxide (CO 2), which can prove toxic to fish.
However, for maintenance purposes the pH of the aquarium water can range from 5.6 to 7.4. However, if captive reproduction is to be attempted, the rummy-nose tetra needs soft, acidic water. A planted aquarium is welcomed by these fishes, particularly if the plants include fine-leaved species such as Cabomba and Myriophyllum.
Ocean acidification means that the average seawater pH value is dropping over time. [1]Ocean acidification is the ongoing decrease in the pH of the Earth's ocean.Between 1950 and 2020, the average pH of the ocean surface fell from approximately 8.15 to 8.05. [2]
Water temperature can be regulated with a thermostat and heater (or cooler). Water movement can also be important in simulating a natural ecosystem. Aquarists may prefer anything from still water up to swift currents, depending on the aquarium's inhabitants. Water movement can be controlled via aeration from air pumps, powerheads, and careful ...
Many marine aquariums include a sump, which is an external container connected to the main aquarium with a water pump. In most setups, the sump is located below the aquarium and is fed water from the main tank via an overflow. An overflow at its simplest is a round hole drilled towards the top of the tank, connected via tubing to an output ...

Water is inexpensive, non-toxic, and available over most of the earth's surface.Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing efficient heat transfer over distance with low rates of mass transfer.
