A modern loop is rarely one metal, copper cold plates, nickel plating, brass fittings. Two dissimilar metals in the same fluid make a battery, and material leaves the less noble surface to feed the reaction. Liquid Utopia plates a molecular barrier onto exposed metal that interrupts that circuit.

01
Why the dose is exact
15 ml per gallon is a coverage figure, not a strength preference.
Under-dosed
Partial film. The uncovered spots become hot spots, worse than not dosing at all.
15 ml / gallon
A complete protective layer on every wetted metal surface.
Over-dosed
No extra protection. It oversaturates the package.

- 1
Leak-test first
On plain water, before you mix anything.

- 3
Fill and bleed
Cycle the pump on and off to push the air out.
- 4
Store the rest
Sealed, out of sun and heat. Use within a few months.
- 5
Check every few weeks
No color means no visual warning. Look for clarity changes.

✓Use with
- DI water, or distilled at minimumNo dissolved solids to deposit.
- Copper, brass, nickel, stainlessMixed metals in one loop is the point.
- Any tubing, acrylic, seals, o-ringsRigid, flexible, rubber, plastics.
✕Never with
- Tap, filtered or spring waterDissolved solids give the loop something to deposit.
- Pre-mixes, kill coils, dyes, biocidesVue, Ice, Pure and Opaque Pre-Mix already carry a package.
- Aluminum componentsNo inhibitor film survives aluminum next to copper.
