Puffers ... Turning Fresh Water ---> Brackish

I'm reading a popular book on marine aquariums The Contientious Marine Aquarist by Robert Fenner and he suggests to mix a little over 1lb of salt for 5 gallons of water. That would be considerably less in a brackish setup.

Anyone out there have general advice for him to go by for mixing brackish water.

I found this as a general guide. "Mixing water for a brackish tank is simple. Create a stock solution by using a good-quality synthetic saltwater mix and adding this water to freshwater at a 10 to 1 ratio." So 10 gallons of water to 1 cup of mix. This will become very easy after doing it a couple of times.
*Remember after the intial mixing up to fill your tank, you only need to change about 10-20% of the water a week. And because salt does not evaporate, use freshwater when adding replacement water for evaporation.


You let it sit overnight to totally dissolve and then test it the next day with either a refractometer or hydrometer. Do a search for refractometer or hydrometer on the internet. Hydrometers can be used for a multitude of things. Search with a fish related key word. Aquarium, Marine, Fish...something along those lines.


And then if you get a reading that you feel is to high, add some freshwater to dilute it a bit...or if the sg is low add a little more salt. It shouldn't be to hard. Just a litte time consuming, letting it sit and testing and tweaking.
 
I am going to be honest .. I am nervous about the whole salt water thing ... only mainly because I can't seem to define how I would measure salt.

That's why I asked if you'd bought a hydrometer yet :) A hydrometer (or more expensive refractometer) is used to measure salinity :)
