I think I got it right -- you are using EXCEL instead of CO2??

Yes, folks add excel, but not CO2.
Excel dosing only.
Non CO2 tanks really leave out Excel dosing, since it's not really dosing CO2 (it is dosing CO2 at the cellular level as Excel decays into CO2 inside the plant).
Excel will not work well on Egeria, Hydrilla etc, they do not have stomata and are more like algae in their uptake of CO2 and HCO3.
And that's why they are very agressive weeds.
