I believe there comes a point for each tank were one needs to fine tune for that particular tank by making small changes followed by observation over time. I would offer the 1st thing to eliminate would be the bottled water. Followed my the chemical filter media. Next would be the Macro ferts.
When one achieves balance of Light, Plants, Fish/Inverts, Water perimeters a tank should be able to thrive with only occasional dosing of Trace ferts. Keep in mind it's a system, not just a collection of parts.
