Hi,
Thanks for your comments.
I have never heard of Equilibrium causing any problems in aquaria. There is always a first time, though.
Compounds containing sulfates are commonly dosed in high tech tanks. K2SO4, MgSO4, and CaSO4 come to mind. I was unable to find any negative comments about sulfates in the APD archives.
Equilibrium contains very little iron, probably not even enough to remediate any significant deficiency. And many say that excess nutrients in a balance planted aquarium do not cause algae.
