Hi everyone. I haven't actually posted here yet. I thought I would start by asking for some suggestions...
I started a couple of walstad tanks a couple of months ago. They did great. I have java fern, anubias, hornwort and duckweed to help with the nitrates and everything seemed fine until the arrival of my wild bettas. When I added the wild bettas I opted to mimic their natural environment and i stained the water tea-colored by adding peat. a month later and it seems like the only plants having a hard time adjusting are the anubias. Everything else seems fine, but the anubias don't seem to be getting enough light. even the cryptocorynes are doing alright.
I'm planning on possibly redoing these tanks in the future.
My question is:
If I plan on keeping the water as dark as it is or if I were to do it again in the future, what are some good plants that can survive and thrive in low light/tea-stained water? So far it seems that Java Ferns and cryptocoryne wendtii. and also can you share your experiences with low tech/ walstad tea-stained tanks?
13 watt. So how big is your tank? And it is several inches above the water surface? It is likely that the light level is pretty low, and with tannin in the water that makes the light even dimmer. If the rhizome was buried, it would rot and the leaves would fall off, not turn brown. Low oxygen in dim light makes it worse as well. Try adding an air stone.
Bolbitis fern comes from fast moving and well oxygenated water. Moss prefers low temps. Tannin is not a problem if you compensate for it with light.

I have Crypt, Wisteria, anubias, java fern, dwarf sag, and a clump of Java moss growing in my NPT now. The bag of soil I used I didn't sift, and my water was tannin stained forever (TONS of wood chunks). Give them time they should adapt. I know Anubias can get rhizome rot and that could cause some of what you're seeing now.
