The salinity of the ocean is also different. When you first enter, the salinity of the water is slightly higher than that of the Yangtze River, but it is not enough to drown. Additionally, the fish themselves also have a wide range. of adaptability
So the conclusion is this:
Under normal circumstances, you will not drown and you will be able to survive;
Otherwise, you will see a large number of dead fish floating on the sea of the estuary. Obviously, that didn't happen.
You can't raise saltwater fish with fresh water and table salt! Because even though sea water is salt water, its salt content is not the same as that of table salt! ! !
Raising saltwater fish is not as simple as you imagine. In addition to sodium chloride, the edible salt we consume every day contains only a small amount of several elements, but saltsea water contains many more trace elements. than table salt and contains more than 20 trace elements such as iodine, aluminum and bromine. Seawater salt specially used for breeding seawater fish can be purchased in the aquarium market. The dissolution of this seawater salt in water is closer to the natural state of seawater. It is still very different from edible salt.
We [not only cannot feed fresh water with table salt, but we also cannot feed salt water fish with fresh water and salt. sea water! _When breeding saltwater fish, only when the entire aquarium environment is close to the marine ecosystem will the saltwater fish survive longer.
The bioliths formed in corals after they have died for many years are the living rocks used for algae explosions. Dead rocks are elementsEssential ants for aquariums when breeding saltwater fish. Because organic stones can purify water quality and bring back the original ecology of the sea.
In addition, breeding seawater fish also requires a complete system, including protein skimmers, filter cotton, pumps, lights, etc. Egg skimmers are commonly found in seawater tanks and can absorb water-soluble waste.
