What do you mean what do you use to refill it? Can you please clarify?
......a month without a water change is waaaaayyy to long. Lots of people do once a week (including myself) and some do every other week, but I haven't heard of someone doing a water change "once a month or so". Maybe some do but that can't be good for the livestock.
Do you track calcium or mag levels? I can tell you that my corals look much fuller and happier the day after my weekly pwc
I think mr. X is right......you need to perform a pwc
and at least do them every other week
