I just bought a new bottle of the fas-dpd powder for my 234 test kit. I purchased the number indicated in the cross reference chart in the sticky above, R-0870. My question is the powder has a different consistency and look. It is more like a powder than granules and is white unlike Ben's which had a reddish tint to it. It appears to work the same but I figured I would ask to make sure I have the right stuff.
