Hello! I recently bought a DPD powder (R-0870) replacement for FAS-DPD test. I noticed the powder is more of a white color, where the previous powder was more of a gray color. Then after adding two scoops of powder to the water sample (10 ml), the water did turn pink but it also is a little cloudy. Before, the water sample would turn pink but be a "clear" pink, not milky/cloudy. Did I get bad powder? I noticed the container only says DPD Powder not FAS DPD Powder, but the number is still the same (R-0870). I can't tell if I got bad powder, the wrong powder, or if something is wrong with my pool water.
