For vodka dosing, they say knowing your Po4 and No3 levels are crucial in figuring out dosing and when to start cutting back.

Or is this one of those instances where dosing the biodigest and bioptum are of real benefit seeing how you can't overdose theses?

I've not had luck with vodka dosing. It seems a balance that is hard to do imo. If your PO4 and NO3 are "undetectable" you just need to watch your tank closely. If you see a decrease in algae then stay at that dose, don't increase. Once the algae is almost gone then you need to back off the dosing. I think the PO4 and NO3 readings aren't are useful as visual monitoring, but give you a good place to start. None of these carbon dosing methods are quick fixes like some people hope them to be.
