Algae problems, Cyano or Diatoms?

[Skimmin]

I like vinegar because you can continue to add it after the problem blooms go away for nitrate and phosphate export. If anything it seems to make my skimmer pull more 'gunk' and there's no excessive foaming whatsoever. You could always message reefwars. Or call Denny at Concept Aquarium in Calgary. He has a wealth of knowledge about dosing and his advice has done nothing but good for me.
