I agree with Paul. Another point to keep in mind is that plants can take up
and store at least some nutrients when concentrations are relatively high,
then use the stored nutrients when concentrations are low. This is true in
many species for iron and probably for other metals as well.
We don't need to maintain constant levels of iron or other nutrients that can
be stored and used as needed. Personally I dose weekly and the plants are
fine. I think the equipment for continuous dosing might satisfy some
aquarists' need to hang more and more gadgets off their tanks. Certainly the
plants don't need it.
