Should I take out the activated carbon that came with the tank? I added it few days ago. I've kept up with my weekly 10% water changes, I do 5liter ones as I account for sand and live rock. I have been feeding a lot more to my fish that probably necessary, because I see that they take few bits and pieces of the mysis shrimp and rest of it falls down so when they leave it there, in my mind I tell myself, it is not enough and ene up feeding more. Quite a lot stayed on the sand bed and when starting the pump back on was swirled around. And when I introduced corals I thought, yeah, they need some food, so started to feed ab+, I thing I have over fed stuff and without clean up crew I have this algae growing. Just didn't know if it's normal or not
