Left my tank for a week without WC (not optimal, I know), and a few days during thanksgiving without monitoring. I was happy to see that there wasn't a huge algae bloom or anything, but I'm really wondering about a few things...
First of all, the petit anubias nana is really turning brown, and smells incredibly mouldy. If it keeps being like this, I'll have to get rid of it because I'm allergic to mould. Is this the diatoms you're talking about? To me, it seems like the plant is just dying.
I picked off the worst looking leaves of the nana, and replanted the tops of the ludwigia because it's growing quite fast with new leaves coming in! It is turning brownish, though, compared to the original bright green. Wondering about some reasons for this? I also removed some melted crypt leaves.
I just did a 80% WC, and added a bit of seachem flourish. The roots are branching out a lot more, and the plants were quite stable when I was doing the WC so that made me happy.
Thinking about getting some invert to help out with algae - does anyone think that this tank could support a MTS in addition to my betta, and would this help with algae? I've read it would, in addition to aerating the sand.
