Removing tank water and replacing with fresh water is not the best way to reduce salinity when dosing two part. Its best to do a lower salinity water change to correct the salinity when using two part. If your at 36ppt and want 35ppt doing a 40% water change at 34ppt would be better than using pure
I think taking a several small amounts of water out and using your ato to adjust over a period of a week or more is better than doing a big water change.Removing tank water and replacing with fresh water is not the best way to reduce salinity when dosing two part.

Unless Randy thinks this is wrong?
I dont do water changes so taking this route is how would do it if needed.
A small change over a period of time is not as much of a shock imo.
