New to this aquarium stuff. Trying to figure out which direction to go. Seeing if it is cyano, dinos or both. They do disappear at night. Leaning more towards dinos. Bought chemi clean. And nitrates because they have been depleted. Read a lot of stuff but they contradict each other. One goes one way the next days the other way. Been manually removing. Then read don't do water change some say do. Nitrate 0.9, phos 0.04 alk 8.2. thank you
