Thanks for the reply, Tom. This tank doesn't have CO2, but I guess I could borrow the CO2 tank from my larger tank for a few weeks.  

I think I'm gonna turn off the lights for a couple of days.  Most of the algae should die back and be eaten by the snails. Then I can do a massive water change.  It might not work, but it can't hurt anything. And it might tip the scales in favor of the vascular plants. 

There is some kind of deficiency here, but I don't know what it is; maybe the plants just aren't taking up minerals with their roots yet, and their reserves are depleted from their previous neglect.  I'll just keep up the water changes and see what happens.

Should I have mixed anything with the Profile, like maybe some sand to take up some of the space between the gravels?

Best regards,
