I'm having some big algae problems in my 75g since I redid it. I'm just using DIY C02 and quite a bit of Metricide. I purposely haven't added any vals or moss to this tank for that very reason.
I've got 6 Nerites in here as well. Going to be adding some Oto's shortly.
Your tank doesn't look bad at all. Personally I'm all or nothing. I would take out anything that Excel will kill and start dosing it pretty good until your plant mass catches up OR add a good amount of additional plant mass.
Personally I determine how heavily my tanks will be planted based on the point when I have zero algae.
