My nitrate test kit was running low a while back so I ordered a new one. Have gone to open it today as bottle 2 has officially run out, and it turns out they've sent me bottle 1 and a nitrite test 
It's too late to send back for a refund, I know this is a long shot but does anyone know of anywhere that sells the nitrate test bottles independently? I've already got a spare nitrite kit so now I have 2, and don't need another bottle 1 from the nitrate kit either!
