    The average salinity of NSW is S=35 What is the Salinity of the NSW in your area?

    You don't need to dilute it.

    100% Lord. :thumbup: That is my thought as well. But perhaps @ianP has made up saltwater or has topped up his tank with RO water for evaporation and now wants to keep the Salinity of the tank and water change Salinity's the same. A little more info please ianP

    OK if you want to keep the Salinity in the tank at S=33 and do a water change, then the NSW salinity will have to be diluted with RO water to bring the Salinity of the NSW to S=33.

    I would rather try and run the tank at a Salinity of the NSW that you collect. I would then do a series of smaller water changes to get them the same.

    Hope that answers you questions. If you are not sure ask and we will help further.
