Hi guys,

purchased a box of instant ocean salt as I am starting to fill up my tank this weekend

I just please need help with this.

the mixing instructions state that for every 1kg salt added will mix 30 ltrs of saltwater.
my question is that do I fill my tank up till full with the ro water
and then do I throw the whole box of salt in and mix

it is a 130 ltr tank,as I bought a 4kg box of salt which treats 120 ltr.

your help is greatly appreciated :m106:
 
Hi Leeg. I personally do not follow the directions stated on the box. It is better to invest in a well calibrated refractrometer. Fill your new tank with RO, then add salt and test, continue adding and testing until the desired SG is reached.
 
fill tank with RO and let the system run, then add salt and measure with a hydrometer or refractometer
 
Agree with all of the above.You can never assume the your water will be the right sg without testing.There are many factors that will cause your waters sg to swing up or down for instance temperature.
