depends on what you afre trying to buffer
There are products in glycol for oxygen scavanging, ph buffering, and usually a film provider to protect new metal surfaces. Also if the freeze protection level drops from water being added you need to boost up the mix %. You can buy straight un-cut glycol to quickly boost freeze protection without needing to swap out a bunch of fluid.
How old is the fluid, what number is dropping. Over-heating is a common cause of glycol failure, installing it in a dirty system, or blending it with poor quality water.

Inhibitor

Just something to boost ph. None of the local supply houses have it and want me to purchase an entire case to get it.
I was thinking , maybe its just soda ash or some readily available industrial chemical.

Buffers:
Plumbers' Supply Company in New Bedford/Fall River, MA has it in user quantities. I'm sure that they would UPS some to you. You need the stuff for aluminum block Weil-McLain boilers. They also have PH meters. At least they have them in the case for display or purchase in the store I purchase from.0 -

Why not use ph booster for spas and pools?0 -

Ask for Dennis Bellanti
He has access to a product produced by a company named Chemical SPecialties, Inc called CST 50. It is a pH buffer.inhibitor for use with glycnoids. It is also used as an anti oxidant in ice cream, so it meets the safe fluid requirements.
I've also used it in non glycoled systems as a water treatment, and have been back to job sites many years later, and the fluid is crystal clear.
Tell Dennis I said hello.

Chemical SPecialties, CST 50
Mark, would you suggest that product (or any other product) for a system like mine that does not use Glycol?
Thank You:
