Just recently there's been brown algae growing like wildflowers on my sand bed. It looks like diatoms that I got during my cycle only this time I can see some of it has hair like algae on it, its not long, couple mm in length in some spots. I don't have any phosphate test kits, but my nitrates are 0 and i have cheato running in the tank now, so hopefully if there are any phosphates that'll help. Any ideas on what this is? and how to get rid of it? i'm thinking cutting back on the amount I feed but when i do feed, i feed mysis, and there is never any left over food hanging around in the tank.
