They actually use RO. I'll ask when the filters were replacedThat sump is fine. It's just different than what you may be used to seeing.
If your leaving the fish why are you taking out the nems?
If they were going to be a problem, they would be dead already.
They are using tap water I assume, Just by looking at it.
