so I have a old refractometer and I haven't been able to recalibrate in a while due to the screw rusting. today I bought a Hanna salinity checker, salinity was sitting at around 1.032. All corals have been looking good except a few zoa's. my question is how fast do a lower it? I was thinking like 1.001-1.002 a day. just wondering what u guys think!
thanks, Logan
