Hey everyone I’m new to the hobby, first tank and it’s been up since February 2020. I have had what I thought was an algae bloom after I put in my first skimmer in a 6 month old tank. The algae was brown and had bubbles in them(not so much any more but still some on wall by top of over flow). Now I’m thinking it’s Dino’s. I’m gonna put a couple videos that I have and sorry the are not exactly looking at the algae. I’m trying to figure out what it is and how to rid of it thanks

You need to upload videos to youtube for them to work best.
