So I set up my new 220 gallon sw
aquarium about 4 days ago. I am starting to see yellow algae (I think) growing on my live rock, also the top layer of my live sand is turning the same color as the rock. Is this algae and it is normal? I tested my water last night and 0 ammonia, nitrate, and nitrite levels. Ph is 8.2. I'm new to the sw
world and will probably be asking a bunch of questions.
