Salinity. How high is too high?

Any chance you can post the product page for what you bought on Amazon. I am in need of calibration solution.

 

American Marine PINPOINT Salinity Calibration Fluid, 53.0mS/1.026SG https://www.amazon.com/dp/B0057IN2SW/ref=cm_sw_r_awd_57ruub08GKE8H

 

I was in the same boat!

My salinity was at 1.30 for about 9 days (I've been neglecting it lately....). The only reason I noticed was because all of my zoanthids were closed up and my starfish hadn't moved in 5 days. Over the course of 3 days I brought it down to 1.25. As of this morning, the zoos are opening up again.

My 3 acros are okay, along with all lps. The birdnest seems to not like the salinity though, as it hadn't extended as much a before.

BTW, I have calibration fluid. It calibrates at 1.026. I've calibrated with R/O and the fluid and don't notice much of a difference (if any at all). NOTE: I don't keep ultra expensive sticks though so I don't have anything dependent on my salinity being that accurate.
