well I had to re setup after a disaster, so I cleaned out everything sterilized the driftwood and gravel in boiling water refilled the tank and waited then added a bristlenose, waited 10 days added a small school of 5 harlequins and then a gold nugget.... all in all its been five weeks now..... after three weeks this fluro green stuff started growing on the top of my driftwood and now its taken over I see it has also attached itself to some plants at the back......I did alot of reading and found that phosphate and nitirite are the main causes....each time I have had water tests done everything reads at zero but phosphates are at 5 - previously I have the same setup with no problems...the tank has been in the same position with the same standard lighting and no issues so I think this might be the cause??
I don't want to use antibiotics because it will interrupt the cycling process which I am still trying to complete properly.... if I remove what I can and get the phosphates under control hopefully this will help control it??
