How do you make 1.007 specific gravity water?

Doeas anyone know?? I want a Figure 8 puffer and was thinking about buying it a 12 gallon bio-wheel fish tank and I heard they do better in brackish water. I also wanted to know how you change Ph of water?? Thank youHow do you make 1.007 specific gravity water?
You need a pack of aquarium saltwater mix and a hydrometer.



Saltwater mix is not just plain salt, it has other minerals that natural sea water contains.



When you get your puffer it will probably be in fresh water, so set up your tank freshwater.



Then when you do your partial water changes add some salt to the new water in the bucket so your hydrometer reads 1.007. Add that to the tank. Keep doing that for a couple of months and you will slowly convert your tank to brackish. Check the tank water with the hydrometer to monitor the progress. Then every time you do water changes, add the correct amount of salt. to the new water.



The other chemicals in the salt mix will tend to buffer your water pH to a higher level to suit your puffer as well.

Requires adding sea salt (not aquarium salt!) and using a hydrometer and/or refractometer to get the degree of salinity and specific gravity.



Don't know the precise amount in tablespoons per gallon....but for ';brackish water'; set-ups there is.....

to help with particular set-ups.

Around 1-2 tablespoons of marine salt per gallon of water or a specific gravity of 1.005-1.010 will be adequate for the full lives of most of these fish.
Use the salt mix for Saltwater Aquariums. This stuff will bring your Salinity up and also your ph.



You will need to buy a hydor meters this will tell you would your Salinity is at.



You might need to just play around with it to figure out how much you need to put in. Add it little by little and check it every-time to see how much you have.
You can change Ph with a Ph buffer I use a product called 8.3 Buffer from Waterlife,
You need to buy a hygrometer which will tell you if there's enough marine salt in your water (buy marine salt, not rock salt or aquarium salt). And if at all possible, don't mess with the pH. Once you start messing with it, it is almost impossible to stablize it and it will fluctuate vastly at random. Another problem would be that every time you did water changes, you'd have to struggle adjusting the pH and getting it stabilized each time, and matching it to the current pH in the tank. Unless your water is drastically far off from 7.8-8.3, it'd probably better to slowly acclimate the fish to your normal pH (most fish (there are exceptions) can adjust to pH that is sort of kind of close to the ideal).
