Local place to get Water Additives?

[Lord09]

I stupidly ordered a whole bunch of WC equipment, but forgot to get some water additives. Rather than place a new order and pay like $5 for shipping, is there any place locally where I can pick up some good additive? I live in Southern California BTW...

Thanks a lot...

NAPA, Autozone, Schucks, ect. The additives we use are intinded for cars, so just about any autoparts store should have what your looking for.

any type of antifreeze with anti-corresive properties is what you're looking for.. if it says it helps heat transfer of the water thats even better
