how to add saltwater fish to an aquarium

your sand into the aquarium and arranging the rock the way you want, you can add the SALTWATER.

The foundation of any saltwater aquarium is, of course, the salt water itself, and through your time in this wonderful hobby, you’ll be mixing up plenty of it! You’ll need it when you first fill your aquarium and , whenever you perform a routine , any time you’re adding and acclimating new specimens, and for any number of unforeseen circumstances that might crop up along the way. It’s always wise to have plenty of extra salt water on hand.
Once the new saltwater is poured, add a high quality water dechlorinator/conditioner to the aquarium.

Once your tank is set up, it's time to add water and salt. Prior to adding salt, add a small amount of water to make sure your tank is water tight. To protect your substrate and rock, pour the water into a bowl placed inside the tank, and allow it to overflow the bowl into the aquarium. Remove the bowl. Once you've determined the tank is free of leaks, add the remaining water and a water conditioner designed for saltwater tanks. Add marine salt until the gravity level reaches 1.021. Use a hydrometer, a tool designed to measure the density of liquid, to determine gravity level. Once this level is reached, your tank is ready for a 24- to 48-hour stabilization period and cycling which, when done properly, can take six to eight weeks. Mix an appropriate saltwater solution and bring it to the same temperature as the aquarium water, then slowly add it into the tank

Removing water from the aquarium and replacing it with new, “clean” water removes waste and organics that are dissolved in the water. It also helps to remove any chemical treatments or medications when the treatment is complete. Dissolved organics contribute to Nitrate and Phosphate build-up that aquarists try so hard to control. These compounds can affect the health of your livestock directly and can promote algae and cyanobacteria growth, making your tank unsightly. Changing the water also helps to replenish minerals and other trace elements. This can be especially important in tanks with corals and crustaceans (crabs and shrimp, both freshwater and saltwater) that use these minerals to form their skeleton or exoskeleton. Corals and other saltwater invertebrates can use up minerals fairly quickly in a closed environment, and replacing old, depleted water with fresh adds these minerals back into the tank.You can’t visually determine the pH balance of the water in your saltwater aquarium. To maintain healthy levels of chemicals and minerals in saltwater aquariums, you have to test the water, and to do that, you have to buy test kits. Here’s a general guide for purchasing test kits for your fish-only or reef tank. As your tank becomes more complicated, you can always add to your test-kit collection.Before you start taking water out of your aquarium, prepare the water you’ll be putting back in. You want the new water to be as close as possible to the old water, especially in regards to temperature, salinity, and pH (only hopefully cleaner). I keep a clean 5-gallon bucket reserved specifically for water changes. If you are using tap water, you can add dechlorinator to remove the chlorine and chloramines. Test the temperature and use a spare to raise the temp of the replacement water if necessary. If you need to use any pH regulators or buffers in your aquarium, now is the time, but be sure to test the water before adding it to the tank. If you have a saltwater aquarium, mix the water ahead of time; a small spare pump can help you get the salt dissolved with little effort.Changing the water in a saltwater tank is a bit more complicated than changing the water in a freshwater tank. However, this task is much easier now than it was in the past. Previously, to add water to a saltwater aquarium, the hobbyist would have to attempt to mix up their own salt water concoction by combining various chemical elements, or they would have make a trip to the beach to collect natural salt water. Thanks to modern technology, saltwater changes today are not nearly so challenging. One-step salt mixes are widely available, making it easy and inexpensive to perform as many water changes as a tank requires.
