I’ve always heard the German made Orion 128, or A322 salinity meters or equivalent combined with a four electrode probe are the gold standard on salinity meters which hold their calibration for years and automatic built in temp calibrations. Very common in laboratory and field studies..New units are a bit outa my league but Ebay seems the most common place where reefers grab them! Good place to start if you want one of the most accurate meters out there!

Yes, those 4 electrode probes / conductivity meters are the ones tested against. I did feel the club should have one, but it was declined as not needed at the time. It could be eye opening how many of us potentially run a different salinity than we think.

Useful! Thanks.
I think my point was that I was wondering if people in general are even aware of needing to calculate that if their water temp is not at 77 at time of measurement

I do think many people know. And the deviation from the temp is not typically impacting the results too much as a large part runs their tanks around that temp anyway.
 
I bought this Zeolite reactor while I was in Germany last week. I was hoping to get this or something similar somewhere here but was not successful. United did not seem to mind the excess weight :). At least, I am able to get the Zeolite media from here (Aquaforest).

It runs a Sicce Syncra 3.0 - for daily 1 min flushing -, and a Syncra 1.0 for 24 hours use.

The reactor is meant to keep nitrates (only) mid-to long term at a low level.

Two downsides right now are that the two pumps with their proprietory connectors make this reactor quite wide - my sump can handle it though - and keep in mind this is the small version, there is a larger version available. The other issue I have, is that my nitrates are currently only around 12 mg/L, so this might be overkill. I stopped carbon dosing about two weeks ago and while nitrate creeped up from around 7 to 12 after a week, it seemed to have settled at 12 mg/L.

The additional change I will make is to reduce weekly water change volumes, which should 'help' increasing nitrates.

I will update once this is running for a while.
