Update: I have decreased light intensity from 70% slowly slowly down to 55% since there was too much green dust algae on the glass every few days. I have started doing water changes every 2 days and also use dechlorinator for my water changes and top-ups. CO2 and nutrients are the same. The plants seem to be growing slowly and steadily but I don't seem to be able to get rid of the filamentous brown algae! I pull it out with the water changes and the next day its there. Another problem that I have is that I did not cut back on the Monte Carlo and it grew thick for quite some time now. This caused the lower layers to melt and the keep on melting. I gave it a trim 2 days ago and now I am waiting for a small recovery so I can trim it down some more so as to expose the melting part of it. I will remove all the melted leaves with a couple of water changes and hopefully it will recover. Also I have noticed that the plants are pearling like mad. Its like a 7up can in there but that doesn't really tell you much. Any thoughts?
