Hi I’m brand new to reefing. Iv had a 10 gallon water box cube set up for around 2.5 months. Got a couple of clown fish that are doing fine. In the last week there has been a massive increase in brown algae. Iv cleaned the glass but it’s all over the rocks and the sand. My LFS said to leave it and ride it out but something doesn’t add up. Iv added a picture. Is this normal? Iv looked at other ugly phase threads and the pictures look nothing like this. All the parameters are fine I’m testing every other day.
