    Hi all
    I wanted to know if there is a
    Formula as to how much salt is needed to raise Your level to a desired result

    I have been away and my salt has dropped off a Little
    I wanted to know how to work out how much salt is needed to get my level back to normal

    Salt level is sitting at around 1.019 and want it o be at 1.024/5
    volume of tank around 2500 liters
    Thanks

    What salt you using?
    There is a salinity calculator somewhere on the net. Will post if i can find it.

    @Visser
    Red sea coral pro but want to buy some additional salt to raise level as I use this for water changes

    Appreciate it you can find calculator

    I wanted to raise my salinity by a similar factor as my initial water came premixed at 1.019. I did 20% water changes at 1.030 for a few iterations to slowly move the salinity up to the required salinity, checking each the tank before and after each time. This gave me a decreasing gradient of change starting at 10%ish and ending at a last water change of 1.026 to do the final adjustment.

    I am trying to establish how much salt I need to buy I don't want to buy a bucket and use half of it
    I buy the red sea as I mix a whole bucket at a time

    I also use red se coral pro. Great salt!
    If i remember correctly, you need to add 36.5g to 1liter ro. For 1.025
    Just use the calculator & add salt till you get the waterchange water's salinity...

    Calculator doesnt seem to tell me
    I understand that the salinity depends on amount I water used , but I need to know how much salt to buy, and then how much water to add to the salt in order to raise salt levels ,
    Water is no concern as it come from the tap , the salt amount is the part I am
    Looking for

    I already have a bucket for my water change , but If I only need say 5kg of salt then I would prefer to buy it loose rather then buy a new bucket

    Well... Its more or less 1gram per ppt...
    So if you need to add 100 liter at 33.2ppt (1.025 sg), you need more or less 3,3kg...
    So 100 liter at 65ppt you need 6.5kg ... Etc...
    You can use the other converter on saltyzoo for salinity conversions.

    Sorry @DeanT, but what your saying happened to your tank doesnt sound possible.
    Please please please check/calibrate your refractometer before you add any salt to increase your salinity!!!
    If your refractometer is wrong, it could be a catastrophy!
    According to my calculations, you need approx 20 kg red sea salt to increase the specific gravity from 1.019 -1.025... In 2500l of water!!! This doesnt seem logical. Where would 20 kgs of salt have vanished to from your tank in the time you werent home?
    Check your refractometer & then still take a water sample to your lps to confirm it!

    If your refractometer is correct, then you need to find the water leak fast! (In which case your auto topup probably kept on replacing the leaked salt water with fresh ro. (602 LITERS to be precise!)
    In which case you need approx 19-20kg of red sea coral pro salt to raise your sg to 1.025!

    Just remember if you increase the salinaty you have to take it up in stages & over a long period of time as a quick jump would shock the LS.

    Checked salinity and double checked with refractometer
    Salinity is definitely 1.019
    So back to my question how much salt is needed to raise the levels

    20kg red sea pro salt @DeanT
    The easiest way to do it safely is to remove about 100l tank water & place it in a bucked, add 5kg salt & mix it. Then slowly pump it back into the tank.
    Do this 4 times over 3-4 days.
    Monitor your salinity after each mixture & on the last mix, you can monitor it for every 25l you add!

    Is there something wrong with the calculator?
