Maintaining algae-free water without constantly increasing chemical levels is one of the biggest challenges in pool care—especially during warm months or heavy use. The Pool RX Black/White (Silver) Mineral Unit (99066) is designed to provide long-lasting algae prevention by using a controlled release of natural minerals that work alongside your existing sanitizer.

Once placed in the pump basket or skimmer, the Pool RX unit slowly releases minerals that circulate throughout the pool, helping inhibit algae growth for up to six months. It does not replace chlorine or sanitizer entirely, but it significantly reduces the amount needed, making water easier to manage and more comfortable for swimmers.

This is a mineral-based algae control system designed specifically for real pool circulation systems—not a short-term chemical treatment.

How Pool RX Improves Water Management

Algae prevention is most effective when it’s continuous, not reactive. Instead of repeatedly shocking or overdosing chemicals, Pool RX provides ongoing protection that supports your existing filtration and sanitation routine.

The Pool RX mineral system helps:

• Prevent algae growth before it starts

• Reduce chlorine or sanitizer demand

• Improve water clarity and stability

• Maintain cleaner surfaces with less effort

Because the minerals circulate constantly, they protect the entire pool—walls, floor, and plumbing—without daily adjustments.

Designed for 20,000–30,000 Gallon Pools

The Black/White Pool RX unit (99066) is sized specifically for residential pools in the 20K–30K gallon range. Using the correct size is critical for proper mineral concentration and performance.

Installation is simple and requires no plumbing changes. Once installed, the unit works automatically as water flows through the system.

Compatible with Most Pool Types

Pool RX works in:

• Chlorine pools

• Saltwater pools

• Mineral-assisted pool systems

It is safe for plaster, pebble, fiberglass, and vinyl pools when used as directed. Because it does not rely on metals like copper in high concentrations, it helps minimize staining risks when water chemistry is properly maintained.

When to Use Pool RX Black/White Mineral Unit

• For ongoing algae prevention without constant chemical adjustments

• To reduce chlorine or sanitizer usage

• In pools prone to recurring algae problems

• During peak swim season or warm weather

• As a long-term supplement to standard pool sanitation
