Inverts accidentally got low salinity

[adova]

I was QT'ing some snails and a tuxedo urchin and I somehow managed to get the salinity down to 1.015. The tank they were moved from was 1.024.

They were very inactive for 2 days and I am not sure if they are alive or not. At this point, should I get them right back into 1.024 / 1.025 or should I slowly raise the salinity over a couple of days?

Thanks!

I've heard in regards to fish they tolerate lowering salinity better than raising it. not 100% if that applies to invert's but as shrimps and the like are considered more sensitve to swings id go with slowly raising it over a period of a week or so personally.

Inverts will survive down until hypo which is 1.008. You may lose a few things but should be ok. Raise it slowly like mentioned above

I lost a few (including the tuxedo) from the initial big change, but all other seems to be doing well as they are on their way back up... Thanks guys.

Slowly ramp it up. Perhaps a tablespoon of salt in the filter a day? (Change according to size)
