Dwarf Sag will grow well and carpet without CO2,at least it has for me.Hygro polysperma grows nicely as well.Hygro cormbosa "kompact" grows very nice under the planted plus lights too.Also,you can put strands of hornwort under rocks to quickly fill in until the other plants get going."Anacharis" IE: Elodea,grows well too,and very quickly.You can also grow Bacopa caroliniana.Thses will probably grow the fastest in a low tech setting.
You can also try java ferns,anubias nana,and some of the other anubias,thought hey wan't grow as fast.
Those are a few of the practically foolproof plants that have grown very well for me,I'm sure others have some too.
MTS? no,I just need one more tank...
