For those of you who use this test kit, what do you do when you start running out of a certain one? can you buy just the nitrate (eg) or do you have to buy a while new kit?
I have a bit of a test obsession, I cant wait for the weekend to test my water and do a pwc and theres 3 tanks in the house, so it takes some supplies
