How ACID Magic® Helped a Denver Rec Center Clean Scale—Without the Shutdown
July 16, 2025
Scale buildup is a persistent problem in aquatic centers, especially in heat exchangers where minerals accumulate and restrict water flow. When Denver’s Montclair Recreation Center faced this exact issue, they turned to CEM Sales & Service and ACID Magic® Multi-Use Formula to find a better way forward.

The Challenge:
Heavy scale on copper tubing inside the leisure pool's heat exchanger was affecting performance. But the facility couldn’t afford a shutdown or added labor for a full system clean.

The Solution:
CEM conducted a four-month in-system cleaning trial using ACID Magic®, a low-fume, user-friendly alternative to traditional acids.

The Results:
  • Visible scale reduction and improved copper clarity
  • Over 1,500 ppb drop in phosphate levels
  • Better water flow and stabilized performance
  • No operational disruptions or added staffing needs
Why It Worked:
ACID Magic® delivers the strength of muriatic acid but with:
  • Low vapor and reduced skin/eye risk
  • No special handling equipment required
  • Safe for aquatic system materials when used as directed
  • The phosphate-free formula helps prevent future algae growth and mineral scale buildup, supporting cleaner water, better system performance, and a healthier aquatic environment—without disrupting pool chemistry.
For municipal aquatic facilities, it's a smart, safe, and effective cleaning solution.
