Biodigest + biopellets

Thanks for bringing this up. I'm constantly forgetting that, and is probably one of the things that keeps me going back to thinking of some form of carbon dosing. I've just always chickened out before doing something.
Question for you Myka if you don't mind (and hopefully isn't de-railing this thread):

For vodka dosing, they say knowing your Po4 and No3 levels are crucial in figuring out dosing and when to start cutting back. But if you can't get an accurate read on those, how do you determine how much is too much? Or is this one of those instances where dosing the biodigest and bioptum are of real benefit seeing how you can't overdose theses?
