So on my 20 gallon long I have an aqueon 36" modular LED light with all 3 LED strips installed (it comes with one out of the box and I bout 2 more for it). They are all the daylight bulbs. I have dwarf sag, hornwort, and a little bit of salvinia minima and my dwarf sag has a little algea growing on them, as well as my aquarium glass. My sand has a lot of brown algea on top of it also. Some of the dwarf sag is like a transparent brown color and looks like it's dying. I'm using root tabs and no c02. Maybe it is the lights causing this? Because all my dwarf sag is green in my 55 gallon aquarium. I run my lights for 10 hours a day. Any ideas?
