| Re: theories of water changes.
Well. the real reason for doing water changes is either to dilute something that is already in your tank (eg. ammonia, nitrates, etc.), or add something to your tank that is constantly going down (eg. Ca. Alk, trace elements).
Technically if you didn't have to dilute anything and you were able to constantly maintain other parameters in your tank, then no water changes are not necessary.
Since most of do not test for everything on a regular basis it would be safe to say frequent water changes would be a safe bet in keeping corals. It is quite easy to dial in your Ca reactor and maintain you alk and Ca and Mg. But do you feel like testing for all the other stuff? |
