I'm dosing 10ml excel daily on my 55 gallon and my vals are doing as well as anything in the tank. YMMV, obs. Too many factors to control for in my pro-plant, anti-algae battle: split photo period (for natural CO2 rebound), excel, flourish, tabs, otos, some out-of-tank H2O2 dips (crypts and rocks, mostly), increased water changes.
Haven't declared victory with all that just yet, but my crypts seem to be bouncing back and the vals are going nuts.
