## Summary description

Aqua-Computer Double Protect Ultra is a 5‑litre canister of PC cooling fluid designed for liquid cooling loops. The formulation provides long-term corrosion protection and biological stability for metal and mixed-metal systems in desktop water cooling. Suitable for filling, topping up or replacing coolant in radiators, blocks and reservoirs; intended for hobbyist and system‑builder use.

## Long description

Aqua-Computer Double Protect Ultra 5 L canister contains ready-to-use cooling fluid formulated for desktop PC liquid cooling loops. The product is intended to provide long-term corrosion protection and biological stability for systems containing copper, brass, nickel-plated parts, aluminium and mixed-metal assemblies. Supplied in a 5‑litre canister, the fluid is suitable for filling, topping up or complete coolant replacement in radiators, water blocks, reservoirs and tubing within hobbyist and custom-built systems.
Advantages
The coolant formulation combines corrosion inhibitors and biocides to minimise metallic corrosion and prevent growth of algae or biofilm in the loop. Its balanced chemistry supports long-term stability in mixed-metal circuits and reduces the need for frequent coolant changes. Supplied ready to use, the liquid eliminates the need for on-site dilution and simplifies maintenance procedures for system builders and end users.
Suitable for
 Filling new custom liquid-cooling loops in desktop PCs
 Topping up existing coolant levels in radiators and reservoirs
 Replacing degraded or contaminated coolant during maintenance
 Use in mixed-metal systems containing copper, brass, nickel-plated parts and aluminium
Key specifications
 Volume: 5 litres
 Form: ready-to-use liquid coolant
 Compatibility: designed for PC liquid-cooling systems and standard tubing materials
 Protection: corrosion inhibitors and anti-biological additives for long-term stability
 Colour: transparent (no dyes affecting optical flow blocks)
How to use
Before use, ensure the cooling loop is drained and flushed according to the system manufacturer’s maintenance instructions. Pour the coolant from the canister into the reservoir or use a filling tool to introduce fluid into the loop until all air is expelled and the loop is fully primed. Run the pump at low speed while bleeding any trapped air via bleed screws or angled fittings. Check for leaks, then top up the reservoir to the recommended level. Follow standard safety precautions: wear gloves if skin contact is a concern and avoid ingestion.
Usage recommendations
Use the fluid as supplied without dilution. For best results, perform a full loop flush prior to filling and periodically inspect the loop for particulate buildup or colour changes. Replace coolant according to system maintenance intervals or if contamination is observed. Store the canister in a cool, dry place away from direct sunlight and keep tightly closed when not in use.
