Firstly, it looks like green cyanobacteria...usually called cyano or red slime (in your case green slime ).

What are all your parameters? Nitrates, phosphates especially, and how bout the TDS (total disolved solids) in the top off water that you use?

do you have a RO/DI system?

 

[kev apsley]

yeah, what kinda of water are you using ro/di? how much to you feed? Do you have a janitor crew (snails+hermit crabs)? looks like a definite water quality issue

I am fighting the same battle with the common green slime and green algae, to be expected with a new setup. I now have an RO/DI system and have been cutting back the lights. We will see and I will cross my fingers, that crap is hard to get off the rock. Good luck....

How much flow and skimming do you have? Also, what kind of water do you use - RO/DI or Tap?

cutting back the lights only postphones the problem until you turn them back on.
You need to find the source of their nutrients(phosphates) whether it be overfeeding, not using r/0 water , live rock in a newly cyling tank etc.

besides the questions above it would be helpful to know if this is a newly cycling tank?
thanks

i use natural sea water, my aquarium is 8mos old....

They are asking about top-off water. You shouldn't be pouring NSW as top off water else you will raise your salinity.

Not being near natural sea water --I am no expert here--but I did read in another forum about an Austrialian with similar problems. People stated that the natural sea water can introduce spores, algae ,higher levels of nutrients etc?

Just a thought
