I don't get why this is beginning to grow in my tank. rodi is comong out at 0 running phosban and carbon thru seperate reactors nitrates almost 0 regular water changes all other tests are good any ideas?

Hope this helps... ro/di testing 0 doesn't really mean your tank water is pure, you could still have phos and nitrates in the tank, have your water tested for phos from someone who has a meter this way you'll have a accurate result, reading should be .002 or lower which standard test kits don't go that low. also test for nitrates anything over .5 could also contribute to it's growth. It could be caused by many things, lighting (old bulbs), bio load, heavy feeding, lack of water changes, leaching phos from rocks and so on and so on.
That is cyano bacteria. How old is your tank? Cyano is very common in new tanks. You can siphon it out and try to increase the flow in the areas you see it.
year and a half running. thanks matt I'll try that.
Definitely not a new tank. How old and what type of lights? You may also want to cut your feedings to every other day.
is it only by the sandbed? It makes me wonder what kind of circulation you have near the sand bed? Typically cyano has a hard time forming if:
there is not a lot of nutrients (whether via water or feeding)
there is a lot of flow
there is a good clean up crew
In that order in my opinion. You could have cyano even with a huge crew - but it's highly unlikely to get any cyano if the nutrient load is low.
On the plus side that kenya tree seems to enjoy it!
btw- you mentioned the reactors - how old is the media? have you changed it recently?

I change it once a month turnover in terms of flow is high but mostly across the top. small powerheads midway but in the rocks. not alot across the bottom. how do I get it down there without blowing everything around? nutrients are not high as I stated in first post. not overfeeding I think? 14 fish 3 tangs, 2 anthius, manderine,2 blenneys 2 cardnals 2 chromis, 6 line and black/yellow damsel
150. gal. only growing in that one spot on sand bed only. I directed some flow downward last night. this morning looking better
