Pool RX Black/White (Silver) Mineral Unit – Treats 20K–30K Gal | 99066
Advanced Mineral Technology for Cleaner, Clearer Water
The Pool RX Black/White Mineral Unit (Model 99066) is designed to make pool care easier and provide lasting results. This system is made for pools that hold 20,000 to 30,000 gallons. It uses natural minerals and silver technology. This helps chlorine work better, fights algae, and keeps your water clear and sparkling.
Instead of always fighting algae and high chlorine levels, Pool RX does the hard work. It lowers chemical use, stabilizes water balance, and cuts maintenance time in half.
Why Choose Pool RX?
Pool RX is trusted by pool owners and service professionals across the country. It improves water quality and lowers costs. By using a proprietary blend of minerals (including silver and copper), this unit:
-
Reduces chlorine use up to 50% by boosting sanitizer effectiveness
-
Controls and prevents algae growth for up to 6 months
-
Improves water clarity with fewer shocking treatments
-
Simplifies pool maintenance by stabilizing water chemistry
-
Cuts chemical expenses and helps extend the life of your pool equipment
How It Works
-
Place the Pool RX unit inside your pump basket or skimmer.
-
As water circulates, the minerals are released into the pool and continuously rejuvenated.
-
These minerals ionize the water, attacking algae and bacteria while supporting the residual chlorine.
-
The result? Balanced, crystal-clear water with less effort and less chlorine demand.
Each unit lasts up to 6 months, after which a replacement is recommended for continued effectiveness.
