No need to buy another test yet. When you have a chance, you could bring a sample of your tank into a lfs for a double check on your numbers. I know most chain stores use strips (which are not very accurate) but I'm just looking for something to double check that your tests are working properly. Just ask for actual numbers, not its 'ok' or 'safe'. If you have a good lfs that uses liquid tests, thats great! I just want to make sure we are not missing something here.
