I’m quite new to planted tanks and have had this tank running for about 4 months. I have been struggling with diatoms (at least I think that’s what the problem was/is). I increased the lighting and have been adding liquid carbon which has made a big difference. However, my Anubias plants are stained brown. I recently pruned them to try and get rid of brown leaves. I have recently noticed some leaves are lighter than the others. Is this just new growth? Also, I have noticed a yellow thing growing from the rhizome. Is this something to be concerned about? I thought it might be the Anubias sending out a flower but wasn’t sure.
