All of my anubias plants in my 55gal seem to grow brown on their leaves algae looking spots and dark green around the outside and shriveled. Also new growth is not growing properly and very slow. I dose excel flourish weekly and API c02 booster daily with a 7gal weekly water change. LED lighting 10 hour cycle. I do notice algae growth in tank is getting out of control I have to scrub glass and filter weekly. Pics attached plants have been in for about a month maybe longer on couple others.
