not sure whats so hard to understand......seems the rest of the experienced reef world gets it so not sure what you question about smaller water changes lol
are you saying that small water changes arn't adequate enough of a practice?
why would you think a larger water change that not only removes but changes the system overall the more the larger it gets is any better than a small one? |
OK, to cut through the chase... Do you believe that changing 1.75 gal per day (ie 16% total vol over 3 weeks) on a 235 gal system is a good regime?? Yes, or no.
As I stated before, even 16% all at once every 3 weeks is not enough vol.
