Can't identify these algae...

I must have grown some new strain of algae nobody has ever seen before!! No, I just haven't been able to find another thread with the same stuff I have.

First, this dark green algae is popping up in several spots on the substrate but nothing on the rocks or glass. This is what I really want to know about:

Then on the other side of the tank I have another type. What I think it is...is just brown algae on the substrate that is catching nitrogen produced by the bacteria in the sand, making it look like bubble algae. But I don't know enough about it, maybe it is bubble algae...


Thanks in advance for your input.

 

red slime aka diatom bloom

 

Diatoms and cyano

 

yep looks like the bubble algae i have in my tank. i blame it on my lack of a ro/di system

 

the red slime is not catching nitrogen from the sand bed... it is just going through photosynthesis so fast that it is forms those oxygen bubbles in a matter of hours

 

if this is a new tank, i would just turn your lights off.

 

Thanks everyone for the quick reply. The lights went out last night and I haven't turned them on until now (10pm). The "algae" has decreased drastically. The dark green stuff looks like GHA but from what I have read it is just another type of cyano. Is this correct? Also, I suppose I need to change my bulbs or at least the amount of time they are on, right?

 

well if you dont have any corals i would turn them off for like a week. ive heard corals can live for about a week without light too.

 

is thewre anything that would eat this algae.

 

unfortunately nothing will eat that stuff you just have to siphon it out.
