While I am not Frank, a little is considered normal (while some will argue it is not), but it looks like where yours is growing is due to lower flow in those areas. With that said, if you cannot increase flow in those areas, manual removal once a week by siphoning it off will be fine also. I have a little here or there in my tank and do not worry about it. It is in low flow sections and it cannot be seen (behind the rocks), so I leave it be for the most part. I may occasionally siphon it out, but I do this knowing it will come back.@fishguy242 what are your thoughts on Cyano? Is a little Cyano ok and normal or do I need to get more aggressive?
With all that said, it is nutrient dependent, so if nutirents are a little high, then you can reduce them a bit to help. You will still need to spihon it out, so other things can outcompete it for nutrients. That is if you really want it done. Even just siphoning it out constantly will give other things a chance to outcompete it.
