The salinity of the sea water tank is generally between 1.023 and 1.025, and the conversion content is about 3.3%, which means that 33 grams of salt will be put into a liter of water. It is worth mentioning that marine fish have a certain range of salinity, not too precise, generally acceptable between 1.018 and 1.028, only a few special fish, the salinity requirements are relatively high.
1. What kind of water to use: Sea water is usually blended with fresh water, while tap water is usually used for fresh water at home. After disinfection by the waterworks, the water is relatively safe, but it contains residual chlorine, so it needs to be exposed to the sun to volatilize chlorine, so as to better fish farming.
2. What kind of salt to choose: Blending sea water cannot use ordinary salt. Salt is based on the characteristics of human health, and the ingredients are often very mixed, so you should choose more professional sea salt. Sea salt mostly uses some imported brands, although there are also domestic sea salt, but the quality can not be guaranteed, the stability is poor, so not recommended.
3. Proportion blending: Blend the sea salt and the processed tap water according to a certain proportion. The proportion has been mentioned above. One liter of water can be added with 30-35 grams of salt. After that, gently stir it. At the same time, use an oxygenation pump to oxygenate it. It can be used after one or two hours.
