Third decan aquarius man/First decan libra woman

Decan-matching is a bit more specific than just straight sun sign. I'm having trouble finding info online about decan compatibility. Any suggestions?

How compatible is the 3-d aquarius man and the 1-d libra woman?

As with cusps, I have a hard time understanding the purpose of decans. In my opinion, they are just a minor influence (if any) compared to other more important aspects for compatiblity. And this may be a reason you are having a hard time finding anything in terms of compatibility online.

I can tell you this...(an example based on sun signs alone)

Say for instance you are a leo in the first decan of leo. Then, you would probably be more compatible with an Aries or Sag born in the first decan of their sign. The reason being because those signs are in the early degrees just like you. And the closer the signs are in degrees, the more powerful the aspect. Make sense?

It will still boil down to the sun sign lol

AND, in your case... an aqua sun and libra sun do NOT aspect each other at all even though they are harmonious.

Best bet for compatibility is to look at moon, mercury, venus, mars (etc..)
