    Hi all. Have bought a 20kg box of salt, as I'm tired of lugging 25l drums from the beach to the bakkie. Now my LFS said I must use 850g of salt per 25L drum? Is this correct? Coz 1 box of salt does 600 litres, wich works out to 30g per liter which is 750g per 25L and not 850 like the LFS said? Which is correct?

    Why not use 750G and Test it to see what the salanity is.

    Can do that, but have read on other forums that its 846g to be precise? Have any of you used this method before?

    Depending on the batch.
    I'm using this salt for over 2 years. In the beginning I found that I need to use about 2.2KG to make 60L. It did not make 600L as the box said, but for the price, I did not care. Over the last year I found that the salinity was actually correct using 2kg per 60L RO. But the last box, was just a bit out again. at 2.1KG.

    So, make it as suggested. Test it and adjust accordingly.

    Hi Travis, there are many factors to consider and like the others said its never exactly as per the indications on the packaging. From past experience, each batch is slightly different.

    A refractometer is a must for any reefer. Please go through the forums on the basics of reefkeeping and read read read before even getting your system started. There are some basic equipment you need to have and some basic steps required before putting any livestock into a tank

    Is there any particular reason why you want to go 5 litres, if you have the space you may want to consider a larger size so that you have more options with maintenance and livestock options

    Good Luck.

    Howsit, don't no where you got that from, as I was talking about doing a water change and wanted to no the quantity of salt needed as I was told 2 diff things I never bought a refroctometer as my water was being tested by my LFS. Thanks for the concern. My tank is already up and running and is stable. And def bigger than 5L. Lol

    At what temperature are you testing the water ?
    I think you should mix the water well , and pre heat to 25 then test...
    The preheated water will also put less stress on the fish when doing the water change.

    Hi Travis

    Im going to be unpopular saying this. [edited out] or better to say, get to know your LFS as some are more better at their quality control than others.

    Having said this, a good habit is to always test the water anyway. Ive heard of a genuine mistake at a LFS where RO was given instead of mixed water and the reefer just accepted that it was salt water and did a 50% water change. You will also be horrified to see the high TDS levels of RO water at some LFS. Mistakes do happen.

    Remember to mix salt powder thoroughly, so as to get a stable batch

    agreed with dallas, Mix the dry salt befor adding it to water, as the difrent particals and elements settle in diffrent layers from the vibration of the transport
