Well, after a couple hours and a sore back I got all the Java and Anubias situated. Some of the roots are floating but the rhizomes are all above the sand now. I only had to use rocks on one bunch and I just layed them on the exposed roots to keep it down.
I also threw in the rest of the polished rocks after cleaning them and now have a bit of a river bed thing going.
I'll take some pics when I get a chance.
We also picked up some better lighting for the hex. I know it is a long shot but I'm hoping the Ludwigia survives.
Thanks again for the advice.
I'm picking up the 75g this weekend. I get all giddy just typing it.
