purplecatfish Posted September 5, 2009 Report Share Posted September 5, 2009 Has anyone here had experience with getting rid of blue-green algae with Furan 2? Quote Link to comment Share on other sites More sharing options...
Stella Posted September 5, 2009 Report Share Posted September 5, 2009 400mg per 100lt. Crush it up (mortar and pestle like) really fine and dissolve it as much as you can in water before adding. Sometimes it kills it straight away, if not, keep adding the same dose for 7 days. Mine just slowly melted away and stayed away. Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted September 5, 2009 Report Share Posted September 5, 2009 if you open the furan capsule and remove the powder - that will dissolve in water really easily. warm water works best. Quote Link to comment Share on other sites More sharing options...
Stella Posted September 5, 2009 Report Share Posted September 5, 2009 oh man I completely read it wrong! :oops: I was thinking the usual erythromycin for cyano, not heard of furan for that. Quote Link to comment Share on other sites More sharing options...

alanmin4304 Posted September 6, 2009 Report Share Posted September 6, 2009 I have used it and it works well. Easier to get than erythromycin which is prescription only. Quote Link to comment Share on other sites More sharing options...
