In the above link to a post, the original poster stated, like I stated, that green is probably the beginning of coraline algae, which is good if you like the look of coraline. He states it takes about a month or so depending on parameters to turn the purple pink color. Mine is similar but had a time when took a lot longer, alk and calcium issues, and when it took less time. Just watch it, if it is a nuisance issue starting you will know quickies if over a few few days to weeks no nuisance stuff, it is just coraline working. Just my opinion, wait and see what happens.
ok so last night i took a tooth brush and attempted to brush away the green from the rocks but it didn't come off. not sure if this is a good thing or bad thing. please help!
Like I said way back on post #2 if it's hard to rub off it's coralline. Remember I mentioned something about sit back and enjoy the color show of lime green to pink to purple and it will all be purple in the end.

Looks like some type of sponge maybe but not really sure from the pictures and my inexperience.
yea im being patient with that... but now I'm seeing something else starting to grow.. it looks weird to me.. they're white-ish/clear tube-like things.. i attached 4 new pictures above.. its not the coralline anymore.
I am fairly new myself but I bought a smaller established, 2 year old tank, that was extremely neglected. It had so much algae and Aiptasia. I did that on purpose so I could deal with all the problems. Several months later it is a thriving tank and I am building a larger setup. Remember patience and do not panic. Typically anything growing is a good sign even if those things growing need to go and action needs to happen. It when things start to die is when there are serious problems. Just my own personal observations about tanks in general.
