I am not sure of the interaction between the various products in the Flourish product line and dechlorinator.
I have often dosed on the day of the water change by dissolving the ferts in the container where I am preparing the new water (including dechlor). I am not using a dechlor or other water treatment that locks up heavy metals.
But then I am also continuing to dose through the week, alternating N, P, K on every other day, and micros + Fe the other days.
I also have a high CEC substrate.
Between all these dosing strategies, if there is a problem between dechlor and fertilizer I am not seeing it.
