I checked against Hanna, I do own some
And Red Sea Test Kits
And Aquaforest test kits
And API test Kits,
And SALIFERT test kits
And Seachem test kits
And Nyos test kits
I ran out of kits multiple times. I think I am going to have nightmare's on the vial test tubes, color charts, small readings on the needles to make sure it was .70 right oh #&#! I have to do the test again.
I sent in multiple water test throughout the testing cycle.
During the peak of testing I was testing multiple tanks, 3 to be exact and a salt mixing station. 1 with no water changes, 1 with Daily and 1 with water changes every two weeks.
