· Nurses Do It Better
I bought a master test kit by Aquarium Pharmaceuticals that contained 7 bottles instead of the 6 that came with the GH test kit. This one contained the nitrate test kit instead. Is AP changing the kit or are both test kits available and you need to know the difference between the 2. Is one an American produst and the other Canadian ???? The one I just boght from Big Als contained the nitrate test kit, while the one i bought last year was at lfs with the GH test.
