Hey all,
I've set up a new tank (log in my signature) 2 months ago. I would really appreciate a hand in identifying 3 types of algae.
Tank is a Waterbox 20, with a 9001 skimmer. Parameters are:
1) First I thought these were diatoms, but there appear to be little strings now. I have these exclusively on the sand bed and to a lesser extend, the glass (I'm guessing my Astraea's are keeping the rockwork clean). There are no bubbles in it, and it kind of follows the outline of the rock. There are almost no algae like this in the areas where there is no light. Hence my diatoms diagnosis?
2) I think these pink / violet algae on the rocks are coralline algae, but would like a confirmation (this is under white light).
3) I have this darker kind of algae growing as well, at first I thought it was a different kind of coralline, then red slime but it's 'dry' and branching. Which makes brings me back to my original idea of coralline or some other macro algae (photo under white light as well). You can also see on this picture that there are no brown algae on the sand bed in this little overhang area (no direct light).
Can someone help me identify the 3 algae?
Thanks!
