The past few days this long, hairy brown slimy algae has been taking over my tank. Most of it is growing on the back and glass. From what I have researched, my guess is that it's either cyano or dinos but I'm not sure which. Ammonia nitrites and Nitrates are all 0, ph is 8.5 and phosphates are 0.05. I am running two AI Prime LEDs at 70%. Tank is approximately 4 weeks old.
