With no conclusive evidence, this is a tough issue to crack for sure Steve, but I am really curious if the filter media change was the winning element here? Could it be that GSA is really water borne algae that evenutally eventually attaches when the timing is right? Is it possible that your media was able to strip it out of the water column?
Don't know much about algae, so I could be just a complete idiot here. But I must say, you went from a very poor condition, to a very positive one very quickly.
Could it be a competition issue with the stems? I guess... but I am not sure how much you have packed in there to draw conclusion on that.
Glad to see you up and rocking again!
P.S. Thanks for the PM.
