Hello, as some of you know I have sold everything from my nano 10 tank. I do have a very tiny pico .75 gal that has 3 corals in it. I need to do a water change on this little tank and would like to know if anyone here can tell me how many "teaspoons" or "tablespoons" of salt for 1 cup of water would equal a salinity of 1.025

after working down the numbers, assuming your salt is 1/2 cup per gallon, to get 1.023, then 1 single cup of water needs 1.5 teaspoons of salt.
But that's for a sg of 1.023, so you'd need to add a couple granules.

Hold on, lemme go back to my drawing board...
Well, first of all, how much salt did it take to achieve that sg in a full gallon?
Different salts have different amounts to add.

Thanks Tizzo, would 1 3/4 tsp be to much then to reach the 1.025??

Ya know what... Try it. Just check it before you add it. If it's to high then you really only lost less than 2 tsp's of salt right?

Hi, I used the water from my tank I just took down so I don't know how much salt it would have taken. I need to do a water change now and so this is why I am asking this. Also, dear sweet beautiful pussy cat just broke my hydrometer that I have had for the past 4 years. I used a glass one and of course it would not work now in this little pico. Don't really want to buy a new one unless I have to so this is why I am asking.
Maybe I will have to breakdown and buy one, I just don't know how well this pico will do so I don't want to invest anymore money into the hobby.
Hope you understand, don't mean to sound harsh

What's in your pico anyway?
I totally understand not wanting to pay more for the hobby, but you hafta understand, they are pets. They will milk you as long as you keep them, lol.
A hydrometer is so basic. That's one of the "must haves".
Even though you seriously downgraded, you will still get milked for...
food,
salt,
tests,
On a much smaller scale of course.
I guess you can take a sample to your LFS and have your SG tested.

But then what you'd spend on gas going back and forth...

I understand where you are coming from and totally agree. I will get one today when I am in town.
I have 1 snail, 1 crab, small frag of neon green button polyps, small frag of green star polyps, small mushroom rock.
I would like to add a sexy shrimp later on when the lfs gets more in.
But I did get a calculation for the salt to water. 1/2 tbsp salt to 1 cup of water.
I will mix this up and then test it to make sure that it is correct.
Thanks again for your help......

I believe it is correct.
You do realize that 1/2 tablespoon IS 1 and a half teaspoons.
(1 TBSP = 3 tsps)

It might be worth investing in a refractometer. On a tank that small, you need to be aware of the quick swings in water parameters and SG might be the most important one. They make it very easy to test SG.
