Is this the correct glycol?

I am so confused.  My Alde reservoir says to only top off with Rhomar RG-RTU-50.  However, I read on a Facebook group that the Truma branded Alde glycol is the same stuff as Rhomar RG-RTU-50.  Is that true?  Can anyone confirm that this is the correct product to order?

To add even more confusion, the NuCamp website sells a Truma/Alde Glycol that they describe as being compatible with model years 2017 to present.  However, its green instead of blue!

    When NuCamp first announced the glycol change back in Dec 2020, the glycol was described as the "Rhomar".  Somewhere along the line, "Truma" simply re-branded the Rhomar into their own "Alde Truma" branded glycol for the Alde.  Same stuff as in your link at Amazon. 
    The earlier glycol installed in the trailers before the Dec 2020 change over was Century brand glycol.  Many owners with the Century stuff in the trailer who changed their own glycol simply stayed with the Century product.
    So: what year is your trailer?  And, as suggested, what "color" glycol is in your expansion tank?

    This may help. I'm (red/green) color blind, but can still tell the difference. Sounds like you have the Rhomar/Alde fluid, so your big concern is to say away from the Century product on the right. The two should not be mixed.

    @pthomas745 @AnOldUR thank you for the help.

    My trailer is a 2025 Tab 400 and my reservoir contains the blue fluid and the sticker calls for blue fluid.  The bottle I got from NuCamp is the green one that @AnOldUR showed.  Confirming I am good to go?

    You mean you have the one marked "Alde Antifreeze?"  That would be the right one to use.  The "colors" here always mess us up a bit.  The important info for you is the year of the trailer.  Every trailer (almost) built after Dec 2020 has the "Alde Truma" antifreeze.
