Have a look at the included image. I am thinking this is black beard algae or stag horn algae, but want to ask to be sure. Right now it is only growing on a small java fern plant in my 40 gallon tank, but I dont want it to take over.
This is a newer planted tank that has a lot of smaller plants in it. I have some Amazon sword, java fern, java moss, hornwort, water sprite, monte carlo, scarlet temple, and a tall plant that I think is vallisneria. I dose a couple times a week with easy green all in one, and I use root tabs as well.
Right now i have a fluval plant 3.0 light that I run at about 80% capacity for about 10 hours, and it is between 20-50% for an additional 3-4 hours. I realize this is longer than many say to run plant lights, but I love the look of my tank in my living room and I like the lights on while I am out there.
So you guys tell me, do I need to reduce the amount of time or the brightness level of my light, do I need a co2 injector, or should I just try dosing with some liquid carbon like seachem flourish excel?
