Need Hanna Phosphorus ULR refill

[reefmaster70]

So I have the Hanna ppb phosphorous ulr checker and I only have three packets of reagent (HI736-0) left. Problem is I can't find refills with this exact number, all I can find is HI736-25

Are these the same? Help!

25 is the number of packets (test) in the box.
