Aquasonic or Aquarium Pharmaceuticals Nitrate Test kit?
I use the AP nitrate kit. The instructions are (1) add 10 drops
bottle one (2) shake bottle 2 for 30 sec. (3) add 10 drops bottle 2
(4) shake 1 minute (5) wait 5 minutes.
I'm not crazy about all the shaking and waiting - is there a better
one out there?
