Genesis1:21 Posted September 14, 2009 Share Posted September 14, 2009 I just noticed these clear or pehaps light purple bubbles popping up on one of my live rocks. They appear to only be on one rock. Do you know what these are? Quote Link to comment Share on other sites More sharing options...
muddybluewater Posted September 14, 2009 Share Posted September 14, 2009 cyanobacteria. Something is out of wack. How old are your lights? What is your water source for top off and changes? How much flow do you have in the tank? Quote Link to comment Share on other sites More sharing options...
Genesis1:21 Posted September 14, 2009 Author Share Posted September 14, 2009 Lights are less than 3 months old. I've been getting DI water from RCA. I have a Tunze Nano Wavebox, 1 Koralia 3 (850 GPH) and a magdrive 700 (700 GPH) on the return. Quote Link to comment Share on other sites More sharing options...
muddybluewater Posted September 14, 2009 Share Posted September 14, 2009 How is the flow in the area where the cyano is? You might try to direct the Koralia towards that area if it is a lower flow area. Have you had anything die lately? Quote Link to comment Share on other sites More sharing options...
Genesis1:21 Posted September 14, 2009 Author Share Posted September 14, 2009 No deaths. I'll add some flow to that area. Quote Link to comment Share on other sites More sharing options...
overkill Posted September 14, 2009 Share Posted September 14, 2009 Lights are less than 3 months old. I've been getting DI water from RCA. I have a Tunze Nano Wavebox, 1 Koralia 3 (850 GPH) and a magdrive 700 (700 GPH) on the return. mag 7 on a 90gal seems small mag 9 would be better ? phosphates? silicates? ultra life red slime remover works well siphon off slime first.

Zarathustra2 Posted September 14, 2009 Share Posted September 14, 2009 having just fought a small battle with this stuff.... Cyano feeds on phosphates for the most part. I got an outbreak after starting to run a media reactor with carbon. I did a lot of troubleshooting but couldn't figure it out. Took out the carbon and siphoned it off and it went away. Did some research. now i run a GFO/Carbon 50/50 mix. Evidently carbon produces a lot of phosphates, especially the amount i was using in my fairly small aquarium. I Also added additional flow to the effected areas and now don'thave a problem. Do make sure to siphon out the cyano during a water change.

innate1 Posted September 14, 2009 Share Posted September 14, 2009 I've been battling this stuff for a while with all my parameters in check. I finally took some water in for Jake to test at RCA and he did a more sensitive test and recommended Rowa over the phosgaurd I was using. I just did this this weekend so don't have details for you but I trust Jake. Quote Link to comment Share on other sites More sharing options...
Zarathustra2 Posted September 14, 2009 Share Posted September 14, 2009 My understanding of it is that most tests only test organic phosphates where cyano doesn't really care whether it is organic or inorganic. Good tip on the ROWAphos. please let me know how it goes. Quote Link to comment Share on other sites More sharing options...
+ACampbell Posted September 14, 2009 Share Posted September 14, 2009 I recommend 2-3 days darkness followed by a water change. Has worked for me in the past. Quote Link to comment Share on other sites More sharing options...

I also did the above to get rid of the issue I had with the nasty slimey stuff. Quote Link to comment Share on other sites More sharing options...
offroadodge Posted September 14, 2009 Share Posted September 14, 2009 +1 for the ROWAPHAUS. i put it in a two little fishys reactor any it took care of my diatom problem and a little quarter sized spot of cyano. Within a week or so. Quote Link to comment Share on other sites More sharing options...
subsea Posted September 15, 2009 Share Posted September 15, 2009 Great comments. One other point is that the chemistr4y in the bulk water column is not the same as the chemistry under the slime mat. Another point for phosphate removal using a macro algae, is that Caulerpa has the highest ratio of phosphate to nitrogen removal from the watyer column by by a facto of 100. Happy reefing, Pat C Quote Link to comment Share on other sites More sharing options...

Happy reefing, Pat C Of course, caulerpa has that drawback of growing like a weed, taking over display tanks, being inedible for most fish, and the high risk of "going sexual".
