just wandering if the salinity in your tank is ok but need to do a weekly 25% water change (kent marine 94lt tank) whats the best way to keep it.
if I add salt water it goes up or ro water down do I have to keep adding a litre of both to lvl it off on every water change is the an easy option to do a water change.

25% old water out, 25% new salt water in.

Do you have an auto top up fitted? This will keep the salinity level ( use RO for top up )
