Our Alde has been in service for a couple of years now, so I checked the fluid to see how it's holding up.
I found two handy & inexpensive devices on Amazon that worked pretty well:
Etekcity PH tester and the
Grand Index coolant refractometer
Coolant will get more acidic over time, so it's a good idea to keep an eye on it, and the glycol loses it's effectiveness over time.
The PH level of the coolant can be checked with a digital PH tester or
PH test strips. PH should measure between 9.5 & 10.5. If it's too
acidic (below 9.5) it can corrode the metal parts in the Alde.
The glycol concentration level (percent alcohol in the fluid) is best checked with a refractometer (a hydrometer doesn't work correctly with propylene-glycol). The glycol freeze temperature should be kept appropriate for the temps that your Tab expects to find itself in.
Just FYI, after 2.5 years, my Alde fluid PH is 10, and the glycol has a -8F freeze point. I'm going to see about boosting that glycol a bit.

I am not having any luck locally finding the Sierra brand.

Dollar General and Advanced Auto only had the Sierra Peak pink antifreeze for water lines. I took a Photo of the Sierra Peak to O'Reilly's and they had never seen it. I did not check Camping World....and I just searched them and Camping World only carries the pink water line antifreeze.

I made the mistake of trusting the salesman at West Marine (he was in a hurry to close for the day, so I didn't take the time to read the bottle), and I found I'd purchased the plumbing antifreeze glycol that they carried.
I've now bought a jug of Prestone Low Tox, and am waiting for a response from them re: how well it will mix with the Sierra that is supposedly in mine. I'm also waiting for a response from Ed Kauffman about how much the system holds, ie: for draining and replacing it.

The manufacturer of the Alde has a recommended change time on the coolant, but I'd wondered how long it would actually last. These give a little more information to go by.
The one bit of info I didn't get was what the percentage/freeze-protection was that LG initially installed when they put in the Alde. ie: if the freeze-protection is only -8F now, what was it when they installed it? I'd think in western NY state, and many other northern states, that -20F would be more appropriate.
A little more info....
"Freeze temperature" is different from "burst temperature" when talking about antifreeze. From what I've read, "freeze temperature" is when the fluid begins to crystallize into a slush, and "burst temperature", or frozen solid, is usually 30 degrees F colder (or more). I'm pretty sure though, that you wouldn't want to turn on your Alde even if the fluid was only a slush. It might be a bit hard on the Alde's circulating pump!

Ed Kauffman sez the Alde system holds 1 1/2 to 2 gallons of coolant.
Prestone sez that their "Low Tox" antifreeze should mix ok with Peak Sierra's propylene glycol antifreeze. Quote: "We haven't tested those two products for compatibility, however they are extremely similar and we would be very susrprised if there was any problem whatsoever with mixing the two of them together."
Now I just have to do the math to figure how much to drain, in order to add the new Prestone, to get -50F protection...
I'm sure I can remember my algebra... I think I can... I think I can...
On another note, I read in my new Subaru's manual today, that they see no need to change the coolant before 11 years!

The map of store locations looks like New York state has banished them.
Closest one to me is in PA.

When I told O'Reilly's it was a glycol anti corrosive anti-freeze for my camper, they immediately went to a new box of Prestone Low Tox that wasn't even on display yet.
