I'm a 2nd fireman, I miss understood something I was told. I have a high pH in the boiler. I know why from research that I did it was from a solution called Sodium Hydroxine i think, aka (Formula 7181)
I added 3mL of this to a tank diluted with water pumping into the boiler to treat low pH. The pH was high at first due to low boiler running. So the chemical built up. I added more to the tank under the impression it would bring the pH down. I was informed by my new engineer that it wasn't correct. I came to the solution fo when there is a large change in boiler water with new feedwater to take the pH and determine if I should run the pump..
Problem, I learned from this mistake but I'm still missing 1 part of my problem. Is there a chemical, or method of bringing down the pH in the boiler without blowing it down?
