Just did a water change using the LFS water I purchased and did a 10% water change. Had a 1.023 salinity before water change and now is a 1.018 now. Is this dangerously low or can I had some salvager as a top off in a few days or do I need to do an immediate change now? Have frogspawn, candy cane, finger leather and pulsing Xenia. Leo have inverts and a fairy wrasse.
Thanks!

I'd top off with saltwater and let it raise up to 1.0264 slowly over time. Salinity drop isn't near as damaging as a quick rise.

I'd probably raise the SG a bit more quickly than that, maybe with some water changes with salt at a reasonable SG. 1.018 might be low enough to kill the corals over a fairly short period.

True I shouldn't assume. I'm thinking of my own evap rate which is fairly high year round and would bring that salinity up at a fairly decent rate but not to fast.
Like I just went through experiencing murphy's law while I was out of town last week and my salinity plummeted down to 30ppt. I just topped up with saltwater and with in a couple days my salinity was back to over 34ppt.
