Any ideas for low-med light plants that could be used to carpet the tank?

I was thinking flame moss or something similar.

This is a low-tech tank. Sand is currently the substrate.

I am doing Micro Swords with Medium Light, they looked like they were melting initially , but after that initial adjustment, they came back nicely and started to spread a bit.
as far as using Mosses for Carpet, you can use almost ANY moss, Xmas, Java, Phoenix, Flame, Peacock.... etc. almost ALL moss will grow in low light.

I've got micro sword too. That initial shock from planting will scare you for about a week, but as soon as you see that new growth you'll be SO excited. :-D

I've been carpeting Hydrocotyle tripartita in my low-tech tank. My current set up is medium lights, dirt + 2mm size gravel.

With that set up it grows nicely, not the fastest but it's noticeable growth in a week or so. Propagates through cuttings and spreads horizontally with good lights + pressing down on the plant gently. In lower lighting set ups it tends to grow a little more vertically. It can also creep onto driftwood and rocks. Great if you want the look of little clovers growing across the foreground.

One thing I have noticed though, it is easy to pull from my gravel if it's not rooted well- your sand may suit it better.
