If there is a significant nitrate buildup, you probably should vacuum.
The nitrate test kit from Tetra is about $10 if you order by mail.

I believe the Tetra tablets contain the major nutrients (nitrogen,
phosphorus and potassium), so they are in a way enriching the
Although many books don't mention it, Anubias nana also grows attached
to rocks, much like Java fern. So I am not sure that it requires a
"rich substrate". If I were you, I'd experiment a bit. You could
potting the swords with a different substrate to see if they do
better. Or try not vacuuming for a few weeks. Sooner or later, you
should figure out what works for you. Alternatively, you could go
the high-tech route.
