Also can anyone ID these particular zoa's I think they are... I know they are small but hopefully someone has a clue of what they maybe.

link one is what we call cyanobacteria. solve this by water changes more frequently. or reducing feeding.

link two doesn't seem too clear to me, how about a close up?

The red stuff looks like cyanobacter.....

the first picture is cyano bacteria. most new tanks experience a bloom. when i had it i syphoned it out with airline tubing (it took about 1/2 hour) and it came back a week later. i did it again and now have not seen it in years....

in the 2nd pic if what you want to know the thing is in the middle is sponge

The first one is definitely cyanobacteria, as mentioned water changes, reduced feedings and more water movement and siphoning it out.

The second one kinda looks like these http://www.zoaid.com/index.php?module=Gallery2&g2_itemId=1619&g2_imageViewsIndex=1 but would need a better picture to be sure
