How much salt to add?

[jamesj525]

This is silly - I know. But the box has no info. Any idea how much salt/gallon one needs to add to get close to a specific gravity of 1.022 to 1.025? A cup? I'm using Tropic Marin.

 

Thanks!

use a hydrometer to be sure.

Of course - I thought they'd give you some kind of starting point on the box. You know, add approximately X amount per gallon, dissolve it, get the temp of the water right, then test it and fine tune it to perfect. I do know, extrapolated from the box, that I should add .124Kg/gallon - anyone know how much a cup of salt weighs???:|

hey James,

do u using cooking cup at home? that what i used my, 2 gallons of Distill water, add 1 cup 1/4 salt , and run it with the power head for 5 mins. untill the salt dissoving. and its always good at 1.025.

i thought the taste test was the best way

 

nah just kidding i used to here that all the time

 

most salt's are 1/2 cup per gallon

 

but use a hydrometer with out that cheep little thing nothing can start off correctly

Thanks guys - that's the ball park I was looking for. I will double check with the hydrometer before I add it to the tank!

 

Good Sailing!

It also depends on your water quality. When the water is pure you'll need more salt to reach the 1.025, vs dirty water. I usualy find about 1/2-3/4 cup per gal, then again I mix 5 gallons at a time.

I use instant ocean and mix 1/2 cup of salt per gal of water. Works great!!

Yea, 1/2 likely. I use Bio-Sea Marine Mix, and 2.5 cups in 5 gallons gives me 1.025 every time.

1/2 a cup worked perfectly - 1.025 on the dot. Thanks again!
