Algae ID Please

I think I know the small bubble one, but wanted to check

Is this bubble algea in the making ?
What should I do for it ?


I had a cool green algae on this one rock, now it is turning red slimy thing.




Any ideas what these two are and if I need to worry ?

Cheers

 

red slime(cynobacteria) and hair algae, phosphates and dissolved nutrients are culprits

 

If it turns out to be Bryopsis, you have reason to be concerned.

 

The green is like very fine blades of grass. The red on top is like a wet dog hair covering the green.

Does that make sense ?

Cheers

 

Well P4 has always tested 0.
My N2, and N3 have been 0 soemtimes small trace Nitrates.

What do you mean by disolved nutrients ?

 

Derbesia then (which is a good thing), once the clean up crew eats it, the detritus won't get caught in it and rot, then the cyanobacteria will go away too.

 

dissolved nutrients, could come from over feeding, decaying matter, or the stuff u feed your corals, atleast if u over feed them. skimmer usually takes care of the dissolved nutrients but it can only do so much, u can get a chemical resin for dissolved nutrients forgot what it was called but i seen it in the shop the other day, i think its from tropic marine

 

Guily as charged on the feeding. Well once a day, but I do tend to overfeed. Judy wamt to make sure everyone gets some...
