This is the only water-column fertilizer I've used for a few years.  I
don't use it regularly.  When I do use it, it works.  It isn't a complete

I think Flora Pride gives just iron and potassium, and it provides a good
dose of both.  If your plants are deficient on either iron or potassium
then adding Flora Pride should get you a readily observed result. I think
you need to use Flora Pride along with the rest of the Tetra fertilizer
regime to get a complete fertilizer.  I quit using the Tetra products in
favor of substrate amendments and the occasional dose of "Plant Gro".
