I probably should have been more clear as to what I think is happening in
my tank. I switched from Duplaplant 24 drops only to Flourish a few months
ago when my plants started showing trace element deficiency.
According to my understanding, Fe++ ions in water will bond to phosphate
ions and precipitate both out of the water. I suspect that while I've been
using Flourish, my setup basically ran out of Fe++ to the degree that
cyanobacteria could take off. I had a mild growth of algae in a deposit on
the floor of the tank. That growth one week converted rapidly from a green
(probably a red) algae to blue-green algae. I suspect that increasing the
iron levels in the water will lower the available phosphate again and
eliminate the cyanobacteria bloom. I intend to do this by adding
micronized iron to my substrate.
My large bottle of Flourish is in the 'fridge. I have a dropper bottle
under my tank that is not refrigerated. Flourish has a different smell
than my Dupla drops, but I haven't noticed anything nasty-smelling. I
believe the directions for refrigeration are there to help keep the Fe
