Product Overview

What pool techs reach for when metallic stains and mineral deposits threaten pool surfaces and equipment.

Packaged in a 2.5 lb container (2.5 LBS net weight), Regal Pool Care System Copper & Scale Out provides a concentrated organic phosphonic acid formula designed to lift oxidized copper, iron scale, and calcium buildup from plaster and vinyl liners. Unlike standard maintenance clarifiers, this full-strength treatment chelates heavy metals to prevent re-precipitation without altering cyanuric acid levels.

Pro Tip

In regions with hard water where calcium hardness runs high, pool heater coils act like scale magnets. Add a routine maintenance dose of Regal Copper & Scale Out monthly to protect heat exchangers and prevent calcium carbonate from crusting on waterline tile.

Common Questions & Instructions

How does Regal Copper & Scale Out remove copper and iron stains from pool plaster?

The concentrated phosphonic acid chemistry binds directly with dissolved metals and surface scale, lifting mineral deposits back into solution so your filtration system can manage them without re-staining surfaces.

Will using Copper & Scale Out affect my pool's pH or chlorine levels?

It will not add cyanuric acid or calcium, but metal treatments can temporarily suppress free chlorine readings. Always balance your water to pH 7.2–7.6 and total alkalinity 80–120 ppm before application, maintaining free chlorine at 1–3 ppm once treatment stabilizes.

Can I swim immediately after adding this 2.5 lb bottle to the pool?

Allow the product to circulate through the filter for at least 15 to 30 minutes after broadcasting around the perimeter before re-entering the pool, ensuring complete chemical dispersion.
