Could I make some questions on your setup...
Why do you have a powerhead rated for a 100g in such a small setup? That's a very strong current.
Why did you mix the gravel with dolomite? The dolomite will consistently increase the hardness of your water and make CO2 injection difficult.
Are you pumping the CO2 through the bubble wand, I hope? If you are using the bubble wand and CO2 system at the same time, you are probably losing a lot of CO2.
------------------------------------------------------------------------------
With the lighting you currently have, I would recommend Cryptocoryne crispatula var. balansae, C. spiralis, or C. retrospiralis. Vallisneria spiralis would also be a good choice for the background plantings.
