Thanks RESGuy.

Unfortunately I might have to rescape. The green plant on the right just is not liking the outflow of the filter at all. It's growing wayyy outta it's way, and it's making the scape look unorganized.
Health-wise, the plants are doing good. The ludwigia's turning red near the tops, the cabomba's turning pink on the tops (yes, pink! I love it), and the other green plant's growing well too (just in the wrong direction). The anubias and java fern are growing like slugs, however. I'm barely getting remnants of a new leaf on one of my coffeefolia plants.
I'm finding it really odd #1 how some of the more harder plants are growing great with absolutely no ferts (maybe because of the uncycled nutrients), and #2 that the easiest plants seem to be fairing the worst in terms of growth.
Algae-wise, my tank is just stuck on diatoms still. I had strands of hair algae on some of my plants from my 20g, but it completely disappeared in this tank. Maybe it's the CO2.
