How much nitrates are you starting with?
As pcw mentioned, choosing between one or two changes, it's a question of whether you are reducing 50% or 44% of nitrates, which in absolute terms could be either a few ppm or decimal points of a ppm. In that context, I'd do 2 changes of 25% to reduce the shock on the livestock.. hope this helps!
