This hub will go over how to mix saltwater for saltwater aquariums.
The supplies you will need are:
- Hydrometer or refractometer - both measure the level of salt ions present in freshwater
- Submersible Heater
- Large mixing container
- Synthetic sea salt - Instant Ocean is cheap and dissolves thoroughly
- Submersible Water pump
- RO/DI reverse osmosis de-ionization water
- dolly (rolling platform) optional
- Place large mixing container onto dolly (rolling platform) - the dolly is optional
- Pour RO/DI water into mixing container
- Add water pump to mixing container and turn water pump on
- Submerge heater in mixing container and set the temperature to 78 degrees
- Slowly pour synthetic sea salt into water and use the hydrometer until the salinity reads 1.025 on the reading scale
- Let the water mix for 24 hours so that Calcium, Alkalinity, Magnesium, and pH stabilize correctly
The next step is to add the newly mixed saltwater to your saltwater aquarium.
- Turn off all aquarium pumps, return pump, wave maker, etc.
- Using a siphon, siphon out 20% of your aquarium water into a container
- Slowly pour the newly made saltwater to your aquarium
- Turn all your pumps back on again
- Always measure the salinity of your aquarium water after water changes and keep it between 1.025 - 1.026
Now that you know how to correctly mix fresh saltwater and add the freshly made saltwater to your saltwater aquarium, performing this maintenance once every week or every 2 weeks will keep your water quality perfect and your saltwater aquarium animals happy.

- You don't need to test how much ppm is for each chemical
- You don't have to worry about what's in the water you're adding to your saltwater aquarium that you obtained from an outside source
- You don't have to waste gas and manpower getting the water from an outside source then bringing that water all the way home to your saltwater aquarium
