Plants can transfer nutrients from older leaves to new growth, so generally I do not remove leaves due to algae unless they are clearly dead (the stem is not green and solid near the base). As I said previously, the aim is to ensure the algae does not increase. What is there is not problematical. In time as the plants settle and show signs of new growth you can remove the older leaves.I removed the worst of the leaves.
Should I remove more?
It has been in the display tank forever, probably, and the guy wants to put in a carpet and this was taking up too much space. If is was in ther for that long I would think it was okay. It's just that when it was in their tank little Otocinlus and shrimp and my hearthrobs ♡♡♡♡♡Panda Garras were always cleaning it!
All of them. Anubias and Java Fern have a rhizome which looks like a thick stem/root; the leaves grow from this, as do the true roots. The rhizome must not bee buried or it will usually rot. The true roots will grow into the substrate depending how close they are, that is fine.Another question, Do I keep all the roots or j
just the bigger ones?
And another. I don't use any fertilizer. I have API Leaf Zone but stopped using; I don't think, overall, that it got s thumbs up on the forum but I could be mistaken.
Plants require 17 nutrients, and these have to be in a fairly specific proportion to each other. LeafZone contains only two. It might help if these two were all that are missing, but not likely. Anubias and Java Fern are slow growing which means they require less light and less nutrients in balance. Any nutrients not used by the plants will feed algae. As will any light not sufficient, too excessive, or the wrong spectrum.What kind of light is required for Anubius and Java fern?
