spamming my way to the top...
Which test kit do you use, and where can you buy them, I'm a bit confused about which one to get as there are so many!
Saliferts are excellent...they are the Merceds Benz of test kits, but, cost similarly. Aquarium Pharmaceuticals (API) are quite satisfactory and that's what I use. I use Salifert for the more difficult tests (Mg, eg). SH
