I just opened a new bottle of dpd powder. I put in two scoops and begin adding drops of fas-dpd reagent. The pink disappears around 2.8 but the water is cloudy. I think my numbers look OK and the water is crystal clear before I put in the dpd powder. I have been testing my water for more than 3 years and I have never seen this problem. All my reagents and powder are no more that 4 months old.

Is this power bad? The color is just off white and it's not clumpy

Any thoughts would be greatly appreciated.
