i am trying to get a better middle reading on this test kit. i know you can dilute 15:1 and use the scale they have in the chart. just wondering if i can use 4 parts tank water and 12 parts ro water. then just multiply the numbers on the dial by 4. Sounds reasonable, but wanted to get maybe Red Sea's take on it.
