I received the kit I order through your link and it came from Swimming pool supply warehouse because Amato Industries was out of stock I guess. I check today and they're back & at a lower price. $87 + $4.34 shipping than what I paid $98 + $6.38. The real problem is when I opened the kit it was filthy & looked like sand was in the bottom. See photo. It turned out the one of the DPD powder containers was empty but, the lid was closed tight. The other was closed and 1/2 full. I check the list here http://www.taylortechnologies.com/pr...asp?KitID=2235 It was missing R-0004-C which I think is the Phenol Red plus the black cap for the PH test tube. If I return it do you lose out on your %, you'll get it back if I reorder from Amato right?
