Brazilian pennywort, dwarf sags, and crinum calimistratum need Co2 replacement like Seachem excel. Vals and moss are sensitive to the excel. Thus you would have to do DIY Co2 for that group.
I found those plants listed as low to medium light / low tech in a couple of threads. I know they are riskier than the java fern, anubias, etc, but think I'll take the risk. Honestly, I wouldn't have the patience to learn DIY Co2. Just testing water parameters is tedious. If the plants don't work, then I'll just have to figure something else out.
Can you get some stem plants like wisteria locally? That would help pull you ammonia down.
There are a couple of sources for stem plants locally. I've had really poor experiences with stem plants in the past and so I'm a little biased against them. Granted, in the past, I naively tried to grow them in gravel under <1 wpg with the stock light fixture.
I thought about using stem plants just to boost the cycle, but I am fairly certain that I'd want to remove them when the cycle is over. Wouldn't that cause a spike in the ammonia? I assumed that the bacteria wouldn't have developed enough to handle the ammonia without the added benefit of the stem plants?
Buying plants is risky now that it is getting cold. The anubias I know ships okay in this weather. Might want to post an add at this form for plants from member in VA.
I will look into placing an ad, thanks for the idea. I may also ask some of the local stores if they might be able to order plants specifically for me.
I really appreciate all the feedback and time you're putting into my little tank.
