Genesis-heat exchanger back-flush

[Beckytek]

I am about to clean my heat exchanger using the method described by Genesis but can't find the Ph-Ospho-RIC anywhere. The Home Depots in my area (South Jersey) don't have it. Is there another source for this product?
If you know of one I'd appreciate it if you could post it. Thanks Ron

It is some times referred to a just "Ospho" and it is available under than name from marine suppliers here in Virginia.

I finally found Ospho on the web at Jamestown Distributors, $16.75 /gal. I have to wait until next week to see how it works. Thanks for the info, Ron
