I am doing something similar. I will have an area with just pool sand. Previously I had a tank with sand as the top substrate. I buried the java fern in the sand. Care of rhizome plants states not to bury the rhizome but they grow fine buried in the sand. At present have a bunch of java fern that just sit on top of the substrate.
I have no experience with injected co2 but I have seen tanks that have lucious plant growth with just injected Co2 added to the tank.
Here is some info on the Bacopa caroliniana:
If lighting is intense and nitrates are low, this plant will turn a dull copper or brownish color. When phosphates are limited, it will attain a pink blush.
So if the Bacopa caroliniana doesn't produce the colors you want adding 5mm potassium nitrate may bring out the pink. I have found potssium nitrate the most beneficial fert to help my plants outgrow the algae.
