30L betta tank, this is after 2 days away, lights hardly on, I did a small dose to co2 and fertiliser. And I had placed Indian almond leaves in too. Is it just the leaves decaying that's causing this, sometimes it's not so bad but after just 2 days I have this mess to clear up. Some things are stained pretty bad like the moss balls. Any ideas?
