Is it better to top off with RO/DI water or already prepared water?
Maybe I am just looking at it all wrong.
Ok... So what your saying is I can't top off my Water with saltwater that's already prepared @ 1.026 since my water parameters are already @ 1.026? What's the difference between topping off with RO/DI water than using prepared saltwater that's already mixed? Then if that was the case then Why even do a water change? I know about evaporation correct Salt does not evaporate. But since it does not evaporate your still having the same salinity if your topping off with RO water than topping of with saltwater that is already prepared and mixed to your desired salinity. And if your doing a water change aren't you changing your water to the exact salinity your gravity is at? Maybe I am just looking at it all wrong.

If you say take 50 gallons of water at 1.026 salinity out of a 100 gallon tank you add back 50 gallons at 1.026 that way in theory the salinity should be exactly the same. Does that help?LOL... I understand the concept of water chemistry and quality just trying to start a debate.... but anyhow if I do weekly water changes and topping off during the week with RO water. How do I know if my Salinity will not raise with weekly water changes compared to topping off and my salinity staying at a steady 1.026? I mean I am using a Refactometer.
