FAS-DPD powder and replacment help

[haeffnkr]

Hello,
Thanks for the quick replys!

So unless the powder gets close to black...and then maybe/maybe not...it will fail.
How long have folks used their powder? 2-3 years?

I will look at my local Leslie for replacements and see what it costs to buy new. Thanks for clearing up the dipper size!!

thanks Kevin

Check the stuff at Leslies before your buy. The last time I looked there the stuff they had on the shelf made Al's look good. It was black as night and one big clump.

You can order the stuff direct from Taylor here.

My Leslies didnt have DPD powder, but rather it seemed like they had a DPD *liquid*? Is that correct?

It was still DPD #1 according to the bottle but the reagent # was different. They were using it to test customer water, and it seemed like they were following the procedure we use with Bens kit, except the first step was to use this DPD liquid. Im assuming thats why they dont sell the DPD powder. If such a liquid exists, Id wonder how/if it subs with bens kits. I hate to have to pay shipping on a little batch of DPD powder, but I will if I have to I guess.
