FAS-DPD powder

You need enough to turn the water good and pink, even red. That's all. More just wastes powder and doesn't change the measurement.

Tayl says to use 2 scooops of DPD powder becasue their scoop is half the size of Ben's. The amount of powder snot THAT critical but the powder dos have some pH buffers in it so I would use the minimum amount called for, which would be one of Ben's scoops or two of the Taylor scoops.

Thanks for the info. I guess you got that info on the website or original test kit because is wasn't included with the refill. Good to know though...

It't not in the testkit either and I'm not sure if it's on the website but Taylor is very good at answering questions! (So is LaMotte for that matter.)
