Yeah hey Sunil that is as far as I can see the only downfall to this. I think as it starts to fade out some, you would get a plankton bloom once again unless you are really staying on top of it. I thought I would try this instead of harsher chemicals. I figured if this works for my FA/Chara even some then I will use it instead of Cutrine. Which don't get me wrong Cutrine works gooooood but figure this dye is not as harsh as Cutrine is overall. If I am wrong about that someone please correct me!
