Hello, I have had my tank up and going for about 5 months. It is a 40 gallon uniquarium. For the past month I've been battling what I thought were diatoms. However, as of recently, it definitely seems like hair algae. My nitrate and phosphates have been under control so I'm not sure what is to blame. I have 2 koralia powerheads (they are not on a controller so maybe that could help) on each side of the tank moving the water in a circular flow. I recently cut down my current usa led lighting from 10 hours to 8. There is a bag of chemipure blue in the sump which has done nothing. Once cycled, I added approximately 1 fish per month to get to where in at now... 2 clowns, 1 banggai, 1 firefish and 1 royal gramma. I'm sure you all may need more info but can you tell me where to start to battle this stuff. Here are some pics.
