Hello, are you using pH test strips? what color does the test strip turn?
The test strip turn a green color like it's suppose to... I went back through the video and the nitrate drops are purpleish... my nitrate drops are brown. I'm gonna get a new kit 405 and try that. The kit I have the previous owner had camewith the burner.
I don't add nitrate to the system just the corrosion inhibitor... the previous owner gave me a gallon of nitrate.
Hello again, I need the brand name and content description on the corrosion inhibitor number, and just in case the same information on the nitrate jug.
