Hi, I'm curious to know if the same reagent is used for the hanna phosphorus p04 checker vs the phosphate checker. It is listed on the package as "sodium disulphate" for the phosphate checker. Has anyone tried buying sodium disulphate in bulk and just measured the weight of the powder in the packets, im using quite alot and looking for a more cost effective way of doing it. Thanks
