How to turn fresh water into seawater for fish farming

To adjust the seawater to the specific gravity of 1.022-1.025 can be, simple is according to the amount of water 2.5% to add salt can be, do not have to be too strict. Use fresh water to flush. Because, tap water to come in disinfectant drugs since, metal elements and other harmful substances more, so to ??? water 15 to 20 days. During this period, add nitrifying bacteria. Cultivate flora, digestion of harmful substances, so that the seaway water as far as possible to meet the required indicators.

Or buy artificial sea salt to modulation, domestic sea salt in the quality of stability is relatively poor, in the not poor, it is recommended not to use. Seafood market used to temporarily raise the "sea crystal", can not be used, that because of impurities, trace elements and other reasons, is not suitable for long-term rearing of marine fish.

Control of Stable Water Quality:

When you start to make a box of seawater, just pay attention to the ratio of seawater per kilogram. The ratio is 30 liters of seawater per kilogram of seawater salt. Most of the modulated seawater pH is maintained at 8.0-8.4, density of 1.020-1.024.0, nitrite content of 0.1 mg / liter or less. Aquarium operation, the usual water will evaporate, the water level will be reduced and the density of the water increases day by day, it is necessary to add fresh water every once in a while to give supplement

Stable pH:

The people who have raised the saltwater ornamental fish know that it is extremely important to maintain a stable pH in the aquarium. Because the pH of the water in the aquarium can drop due to residual nitrites and nitrates, it must be tested regularly to avoid deteriorating water quality, which can lead to discomfort and disease infection in the fish. It is important to realize that the vast majority of large and small white spot diseases common to saltwater ornamental fish are contracted as a result of excessive pH changes.

Partial water changes on a regular basis:

Nitrate cannot be broken down by nitrifying bacteria, and some removal methods are too costly, so when nitrate accumulates to a certain level, it can lead to algae such as Trichoderma, Haplococcus, Filamentous Algae, Brown Algae, and even Red Algae blooms. This not only affects the aesthetics of the aquarium, but also causes a certain infringement on the fish or organisms, which in turn destroys the ecological balance of the aquarium and leads to flooding, which can not be described as serious.
