    Hi Guys,

    By now most newbies like myself know to use only RO water in our systems (thanks to the MASA guys :thumbup:). I also know that we only top-up with RO water and not saltwater as only (or mainly) the water evaporates.

    Can anyone tell me what the correct (common) way is to mix RO water and salt (Quantities)?:p

    cdupreez....quantities will rely on the brand of salt used...I use Tetra and 1 kg makes 25 L.

    as for how to do it I chuck my water & salt into a large bucket , run a pump inside and heater. When temp is right i do the change.

    Hopes this answeres your Q

    Agreed! Depends on the salt. I always get temp right, airate it and double check salinity before adding.:)

    The easiest way is, get another tank (a small one)... When you are ready a few days before the change, do as FransSny said ... add RO + salt + heater + a pump or air stones to let the water circulate. Get it to the right temp.

    When you are ready, change the water accordingly.

    Just note, when mixing the RO and salt, take baby steps, mix a bit, check the salinity and continue on the same path, until the requirement is met.

    I have a spare tank, and when I need water, I just check the salinity and use. :)

    Also some salt you need to leave airating for at least 24hours before you can add it.

    FransSny has it right, but just remember - it is best to heat up the water before adding the salt as it dissolves better. Always add salt to water and not the other way around as it will become cloudy/milky. I let mine circulate in a 120litre food grade bin at least 24hours before I check the salinity and adjust if nesseccary. It is good to always have ready made saltwater at hand incase of emergency ;)

    Thank you Frans, I will need to get extra heater and pump. You mentioned that you use Tetra salt the LFS closest to my only sells Tropic Marine Salt (I know their test kits are good), would you recommend their salt?

    Tropic Marine salt is really good but it is really expensive when compared to other top brands. I prefer it to tetra though. Just make sure you use the right one, there is one for mainly fish only systems and then one for reef systems.
