Two bottles is what you need the first time you fire up a 10,000. After that, 1 gallon will last you a long time. At the start of each season, I typically have to add from halfway down the gauge to full, and I add 1/4 to 1/2 a gallon then send in for testing. Your numbers will be less running the 5,000. That was a good gift. It's about $70 per bottle.

They changed which water treatment they recommend about 5 years ago. If he bought his furnace since then you should be alright.
