Diatom Outbreak to Brown Hair Algae?


New member
Seems what I thought was diatoms, seems to be getting hairy looking and brown on LR and sand, I know my tank is still cycling, is the brown hair algae part of the cycle as well? Let me know I can should do anything differently,

Yes it is part of the cycle, first the diatoms, then the hair algae, then cyano.
You could lower the lighting times on the tank by a few hours a day to help.

Yeah it is a part of it! It is just a part of it... Dittos with Blown 346, decrease your lighting do that it doesnt promote more growth then you already have...

Diatoms are a normal part of the tank cycling. You might be experiencing a bit of hair algae which is typically green, but might look different under your lighting. Both are part of the cycling process. I would just let your tank do it's thing and it will pass on its own. Can you get a pic of the algae? Typically brown stringy algae along with bubbles is dinoflagellates. This isn't an algae typically seen during cycling.
