drop in salinity

[reef101]

i was wondering how much of a drop in salinity can SPS and clams tolerate. For say a drop in salinity due to evaporation, when the salinity was from 1.023 and went to 1.024. WOuld this be fine or no?

I've had my salinity change a full point (from 1.025 to 1.026 for instance), and all corals (including SPS) seemed to do fine. I try to keep changes within half a point though, since it's not too difficult with the auto topoff I now have. I wouldn't worry about one point, but I'd try not to go beyond that.
