Weird Algea like Phyto


Active member
Well since my tank is about 1 1/2 month old seeing allot of Phyto like Algae on my rock and glass... I just started running GFO a couple days ago and it doesn't seem to be working lights are on about 8hrs a day.... Just wondering if I have to do something else to fix this problem...

Diatoms? Do a google search in images for "diatoms on rock"

If that is what it looks like you have nothing to worry about. All new tanks usually get them and they will go away on their own. You will just have to ride it out.
