Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to acclimate salt water fish [title] Measure the specific gravity of your tank. [step] The specific gravity of a body of water is its relative salinity in relation to pure water. A higher specific gravity means that there is a higher percentage of salt dissolved in that water.

Ending1: The higher the gravity, the more salt the fish will need to process. The average weight of fish will be approximately 42 kg per pound. Ending2: You can measure the specific gravity using a refractometer. These devices can be purchased through an online retailer or from some pet stores. Ending3: As a result, you need to figure out which laws and regulations dictate the exact gravity of the water in which you'd like to place your fish. [substeps] If you have saltwater in your aquarium, you're dealing with a bottom reef. Ending4: A higher specific gravity means that seawater is more likely to contain more salt. Let's understand the ratio: the low salt water scum form the water of your local water tank, while the high salt water scum forms the water of the ocean.
