POOLRX Plus Pool Unit Black 20K-30K Gal
Product Overview
Mineral-alloy cylinder designed for continuous six-month algae suppression in 20,000 to 30,000 gallon pools.
At 1.2 lbs, the PoolRx+ Black Pool Unit (SKU 331066, EPA Reg # 79817-4) installs directly into the pump basket to release an active mineral blend of Copper Sulphate Pentahydrate 86.85%, Zinc Sulfate Monohydrate 1.51%, Silver Nitrate 0.40%. This formulation eliminates algae continuously across a six-month service life, supporting clean water while allowing residential chlorine levels to sit between 0.5 and 1.0 ppm, or commercial pools between 1.0 and 5.0 ppm.

Product Details
Copper Sulphate Pentahydrate 86.85%, Zinc Sulfate Monohydrate 1.51%, Silver Nitrate 0.40%
One 1.2 lbs unit treats 20,000 to 30,000 gallons for up to 6 months; maintain 0.5 to 1.0 ppm residential free chlorine or 1.0 to 5.0 ppm commercial.
Compatibility
- Compatible with chlorine, salt chlorine generators, UV, and ozone systems.
- Do not use with heavy metal-chelating or metal-sequestering products, which strip the active mineral residual out of the water.
When To Use This
Pro Tip
In hot climates where intense UV rays strip free chlorine quickly, this mineral residual stays active even when sanitizer levels momentarily dip, preventing flash algae blooms before your feeder catches up.
Common Questions & Instructions
Where should the PoolRx+ 1.2 lbs unit be installed for best results?
Place the unit into the pump strainer basket for maximum circulation, or in the skimmer basket if the pump basket is inaccessible. Run your pump for 3 to 4 hours immediately following installation so the granular formulation dissolves through the filter into the pool.
Will the PoolRx+ Black Unit SKU 331066 alter water balance parameters?
No. The unit does not introduce cyanuric acid, nor does it swing pH, calcium hardness, or total alkalinity. Keep your chemistry balanced at pH 7.2–7.6, total alkalinity 80–120 ppm, and calcium hardness 200–400 ppm before inserting the cylinder.
How long should I wait to clean my filter after installing the PoolRx+ unit?
Do not clean or backwash your pool filter for at least two weeks after installing the PoolRx+ unit. The active mineral granules settle into the filter media to dissolve into the water column, and backwashing prematurely will flush those minerals out of your system.
