Franklin Machine Quat Ammonia Sanitizer Test Strip Tape

i was using this to test ammonia levels in my aquaponics set up. doesn't show the ammonia yet the fish are stressed out, and i know there should be ammonia in the system by now, and the nitrofying bacteria colony has barely established itself.

These work fine, but the label is stuck right over the color matching guide. Not at all helpful.

Doesn't work .... I bought to be cheaper than than the liquid test... and they show no ammonia but my liquid test showed 2.0 ammonia... don't trust test

Great product!

did not work for me

My order came on time and quickly. Test strips needed for my culinary arts classes are hard to find in local stores.
