Three more months, then you'll need to get that newer larger tank.Might as well order it now so it will be on hand in time.
That or start keeping a few Angelfish.

Bax: Thank you very much.
chrismunn: I really have no clue as to how much water is being displaced by coral. A horrible thought but I suppose that if one were to grind up all the SPS coral in the tank, it would actually only take up a relatively small amount. Maybe 30-gallons or so? Again, I have no clue.

Any difference in water quantity due to ever expanding corals has no bearing on evaporated water altering salinity. This, due to the constant replenishment of top-off water. But I have had to run my calcium reactor much harder to keep up with the growing calcium demands. Currently, I have my bubble count at roughly 120/minute. I also added some time ago the evaporative cooler to my sump. This aides in temperature control but perhaps more importantly, allows me to add more Kalkwasser to the tank via the top-off water. I do definitely have to replenish the calcium hydroxide more now that this cooler, along with a high air turnover within the room, has been added. All this being a good thing for a highly demanding, SPS dominant tank. In addition, I have to add more liquid magnesium now than I did before.
