I've been using premixed anti-freeze. No more chemicals to worry about in the tap water.

In my experience you can't eliminate galvanic action on aluminum. The thinner it is, the bigger the problem.

The aluminum fins on the a/c condensers here suffer the worst. There seems to be no way to neutralize it and with the rock salt used here in the NE, the stuff grows on the cars even in a sealed garage that never sees salt itself.

The only thing worse that I can imagine would be living right on the beach with a salt water source right there. The salt is going to be in the air.

Zinc is used on galvanized metal here simply to attract the action to it rather then the metal it is protecting, which is usually steel.

There is no way to eliminate the process, just slow it down some.

There is only a one year warranty on the Fluidyne. That alone tells me volumes.
