Random question can anyone confirm if the reagent changed for the Hanna 781 low nitrate. There website now shows just a bottle and a packet and no longer the bottle two packets and little coffee filter that you had to use. Still have a bunch of this old stuff left to go through, but if they made it a lot simpler I’m im tossing the old and buying this simpler version instead lol
