I have the liquid amonia test kit from Aquarium Pharmaceuticals - the one where you take 5ml of tank water, and then add 8 drops from bottle 1 and then 8 drops from bottle 2. Shake and wait for 5 minutes and compare it to a color card.
I've been using this same test for months. Today, however, my saltwater test is showing up white. No yellow. No green. Just white. I've attached a picture.
So, then I went out and bought a new test to see if it had expired, and I got the same results.
Ive attached a picture.
Any idea what is going on with this reading?
