Yeah, pretty much what I had.
Simple and low maintenance.
Maybe combined with a better more interesting fuge....

It is definitely useless at too high of a flow.
But UV is no miracle cure. You need to be reasonable on what to expect.
Will it cure Ich, reduce Nitrates/Phosphates - NOPE.
I see it having two uses:
1) Keep water crystal clear, and eliminate yellowing.
2) Act as an insurance policy of sorts.
- Eliminate algae blooms.
- Eliminate bacteria blooms.
- Reduce the chances of Cyano/Dinos/other bacteria.
- Reduce the chances of the spread of ich and other diseases if I get them.

Well, because of calibration fluid issues and Apex salinity measurement, I overshot the salinity.
Not by a ton, only 36-37.
But enough that I have to do quite a few small water changes, replacing salt water with RODI.
Not sure what it is, but my Apex salinity measurement sometimes just is off.
Like below. Around noon, I added the very well cleaned rock to the tank.
Nothing else. No salt.
And salinity jumped like crazy. (To the correct value)
Weird.

Have a refractometer to test it against?

Two. (one pretty old, with issues)
But my calibration liquid was old, and off.
And calibrating to RODI made nothing match.
Now that the Apex is working and I have new calibration fluid, all 3 match well.

I changed my Quarantine system a little bit.
Before, I pumped water from display tank, to QT, and let overflow and gravity fall
back through a 5 micron filter to display tank.
Non stop high volume water changes.
But it means replacing filters. Not expensive, but if I forget, and they clog, it will overflow
unfiltered into the main tank.
So now it is on my automatic-water-change.
As it does AWC, it pumps water out of display tank and into quarantine tank.
That overflows and now goes out to a drain to be disposed of.
Far less water than before, but a lot safer.
And at around 2 gallons/day, in a 20G QT, that is 10% per day, which should be plenty.

Are you pushing through the filter still into the qt? This is basically what id like to setup at some point.

Air bubbles in your probe? Is it near your skimmer or drain pipes.

Not anymore. Although I could rather easily.
But why? My display tank water is good.

I did shake it and clean it when I was having issues the day or so before, but maybe.
I have had similar issues before when adding fresh salt water. Might be something to do with that.

Neat idea. Yes I could have.
Salinity is now fixed anyway, after lugging buckets....

Did some water testing during lunch break.
Salinity is good, a bit over 35, but barely.
Magnesium was a bit low but ok at 1300. Added some.
Calcium was great at 480.
Alk was low at 7. Fixing that, but slowly.
Ammonia and Nitrite are not zero, but pretty close. Both < 0.25.
Nitrate was zero, which is a bit surprising.
So a bit of tweaking needed, but overall quite happy.

Corals are not in directly, but are getting water from main tank now, through auto-water-exchange.
My QT is a bit small, and I put a lot of the old corals in there, so can't really keep it separate long term.
