Help "Quick Primp" and L Repens (56K Warning)

I posted this on another forum, but am hoping for some pointers regarding my L Repens:

I have two questions.

First off there will be a little get together at my place next Monday, 10/03/2005. While my tank is in my basement, I can be pretty assured at least some of the 100 or so people will make it down to see it. What can I do to prepare it to look its best?

Second, what is going on with my L Repens. It has never grown well. At one point took a single cutting and placed it in the center of my tank. It has taken off. It is now doing better than the rest in the tank. I don't think it is getting more light, but everything else should be equal.

Here are the pics. They are linked to my blog/image hosting, so if you can't see them, you can click here: http://goodrichbloggers.blogspot.com/

This is where I am thinking of the biggest changes. I tried HC, but have seen ZERO growth in nearly a month. I am thinking of taking out the L Repens, and spreading out the Dwarf Hairgrass, or the Dwarf sag on this side.

Is it too much CO2 then? I haven't heard of that, but the plant that is doing well is in the middle of the tank about two feet from the output. The deficient plant is very close to the output, and at times has Super Saturated water and CO2 bubbles flowing around it. How long would it take to recover from a deficiency? I have been dosing Mg for about two weeks, as I thought that could be it, but I can't figure out why the healthy plant wouldn't suffer from the same deficiency.
