Darryl Mcg Posted February 3, 2006 Report Share Posted February 3, 2006 Can someone out there confirm and advise please. I have a 215L AR980 Tank established 12 months ago. Have never had any issues with sick or dying fish. I run an additional external Eheim Classic 2213. I do 20L water changes every week and 40 L every 3-4 weeks In the last 3 months I have noticed a progression of a darkish green coating appearing on any plant life/Bog wood that is above 3/4 of the water depth. At first it looked like a green stain. After several attempts to remove it manually and confirming it is definitely a closely matted weed of some sort. Any way no amount of vaccuming and siphoning has made a dent in it really. It is now starting to appear on the glass and lower plantings. Somthing is going on. Any enlightening replies most welcome Darryl Quote Link to comment Share on other sites More sharing options...
Ira Posted February 3, 2006 Report Share Posted February 3, 2006 A weed? Hmmm, I'm betting it's actually cyanobacteria. Slimy blue greenish mats? Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted February 3, 2006 Report Share Posted February 3, 2006 If it is blue green algae it has a distinctive smell Quote Link to comment Share on other sites More sharing options...

alanmin4304 Posted February 3, 2006 Report Share Posted February 3, 2006 Syphon a bit out and smell it. It is a distinctive smell. Quote Link to comment Share on other sites More sharing options...
Darryl Mcg Posted February 3, 2006 Author Report Share Posted February 3, 2006 Thanks for the replies. In bright light the colour is light green in the shade it appears darker (mmm). I have never detected a hint of purple. It can be cleaned off leaves quite easily using fingers and dislodged from the bog wood with a bottle brush. When examined close up it appears to be a weed, but very interlaced and able to be removed in blanket like segments. Hence my initial query could it be blanket weed?

Darryl Mcg Posted February 3, 2006 Author Report Share Posted February 3, 2006 Also forgot to mention the smell under the hood is quite normal. Quote Link to comment Share on other sites More sharing options...
fishy family Posted March 4, 2006 Report Share Posted March 4, 2006 I think I have this in my tank too. Looks like the driftwood has been dipped in paint. How do I get rid of it? :bounce: Quote Link to comment Share on other sites More sharing options...
Aaron_fish_mad_guy Posted March 14, 2006 Report Share Posted March 14, 2006 janola works , take the offending piece of wood out , bleach it.... then submerge it in a bucket outside in FULL SUNLIGHT for a week. That should kill anything! 8) Quote Link to comment Share on other sites More sharing options...
