2 algae I.D's please

[EVReef3]

1. im starting to notice this a lot on my live rock.. its even on my glass scrubber now. It feels like grass, it can be pulled out but hard to take it out because the bristles are small and just float away..


2. The last picture: I noticed this spot on one of my rocks a few months ago, now its gotten very big and doesnt look very attractive. What is it? how can i treat it?

Please let me know, thanks.

How can i treat it, any ideas?

My levels are fine, i feed every other day, and only enough so they eat i all.

well if your not overfeeding. what kind of water are you using? if its tap then try rodi water. and what are your nitrates and phosphates?
do you have a good skimmer. cyano is from extra nutrients in your water,everyone has had cyano from time to time. just do weekly water changes with rodi water and suck the cyano out when you change your water and it will go away. and it can be from not having enough flow
