## Summary description

Aqua-Computer ULTITUBE D5 50 PRO is a cylindrical coolant reservoir designed for integration with D5-series pumps. It provides a compact mounting option for custom liquid-cooling loops, offering secure attachment and fluid containment for PC water cooling systems. Suitable for builders who need a dedicated reservoir compatible with D5 pump hardware and standard loop components.

## Long description

The Aqua-Computer ULTITUBE D5 50 PRO is a cylindrical coolant reservoir engineered for integration with D5-series pumps. Designed to sit directly above or beside a D5 pump head, this reservoir provides a compact and stable fluid container for custom PC liquid-cooling loops. Its form factor supports secure attachment to pump housings and standard loop tubing, helping maintain coolant volume and flow stability in desktop water-cooling systems.
Advantages
The reservoir offers a space-efficient cylindrical design that minimizes footprint while providing sufficient coolant capacity for small to medium loops. Constructed to align with D5 pump dimensions, it simplifies installation and reduces the need for additional mounting hardware. Clear material and visible fill level allow straightforward monitoring of coolant level, and the sealed interfaces reduce the risk of leaks when connected to compatible fittings and pump housings.
Suitable for
 Custom PC water-cooling builds using D5-series pumps
 Compact or mid-tower systems where space-efficient reservoirs are required
 Loop configurations requiring a dedicated reservoir and visible coolant level
Key specifications
 Cylindrical reservoir shape optimized for D5 pump integration
 Compact dimensions suitable for small and medium enclosures
 Transparent/visible body for coolant level monitoring
 Mounting interface compatible with D5-style pump heads and standard fittings
 Sealed connection points to maintain loop integrity
How to use
Mount the reservoir to the D5 pump housing or adjacent bracket following the pump manufacturer’s mechanical alignment points. Connect inlet and outlet fittings to the loop using compatible tubing and fittings, ensuring all threaded or push-fit connections are tightened to the recommended torque and sealing method. Fill the system with appropriate coolant while checking for leaks at all joints, and run the pump at low speed initially to purge air from the loop. Monitor the visible coolant level and top up as necessary after bleeding and stabilization.
Usage recommendations
Use corrosion- and algae-inhibiting coolant formulated for PC water cooling. Verify compatibility of fittings and tubing diameters with the reservoir and D5 pump connections before installation. Perform leak tests at low pump speed and recheck seals after several hours of operation. If the reservoir shows signs of discoloration or deposits, flush the loop and replace the coolant according to coolant manufacturer guidelines.
