So I use Hydros. It's easily expandable, etc. Look at the Hydros Launch. It should do basically everything you want there.
The Hydros salinity probe is pretty solid after the 3-4 week "break-in period" that Hydros has. I haven't calibrated mine in 6 months and it's still right in line with my Milwaukee.
I make small adjustments all the time, though I usually do the adjustment with my weekly water change. My new saltwater going into the tank is either higher or lower depending on my level in the tank. Typically it's usually a bit higher due to skimmate having been removed during the week.
You want to keep these all in line for the health of your livestock and coral. I monitor dKH most, with 2 daily tests. Salinity gets measured the same, but that's simply because its part of my alk tester.
Thanks, that makes sense. I forgot about skimmers removing a bit of saltwater . I don't normally run skimmers.
Interesting, so do you at least clean it once a month?

I find that mine starts to drift after few weeks just from biofilm growing on the electrode. They are all measuring conductivity and biofilm tends to impacts that reading.
I have to confess, I am lazy so I rarely calibrate mine (4 times in last 5 years), I just keep it for trends. I would never make any changes based on it, for that I use this:
nope. It sits in the IV and I dont touch it. The pH probe though, that I have to calibrate monthly.
