Newish tank about 5 months....is this hair algea, diatoms, or cyano? I am trying to be kinda hands off as far as it being potentially the "ugly stage" and let it run its course but now I am not sure. Thinking it might be ditoms I found a thread that said try raising the temp and figured that won't hurt to try....well it got worse. I will have to run tests tomorrow to get better specifics on parameters but I am hoping someone can just say...ugly stage leave it or cyano treat with xyz. I am tempted to add uv before adding chemicals but I am not sure
