101001 Blue Mineral Unit 7.5K-20K Pools by PoolRx


PoolRx contains a proprietary blend of minerals that continuously and effectively eliminates algae. The specially treated alloy cylinder is packed with the PoolRx mineral formulation. These minerals immediately dissolve out of the cylinder and form a stable residual throughout the pool water for up to 6 months. The minerals eliminate the algae while freeing up low levels of chlorine to be more active and productive in the water. During the pools filtration process the minerals are rejuvenated every time they return and pass through the cylinder. PoolRx works synergistically with a constant low level of chlorine. Residential (0.5-1.0ppm); Commercial (1.0-5.5ppm)


PoolRx Minerals improve the salt water experience. The minerals reduce the salt chlorine production needed to keep your salt pool sanitized and algae free. Less salt chlorine production extends the life of the salt cell and reduces the amount of acid needed to balance the pH.PoolRx prolongs the life of your equipment, saves you money and improves the quality of your water.PoolRx is a unique chelated mineral algaecide and chemical reducer that saves you money and simplifies maintenance while improving the look and feel of your water. PoolRx is effective for up to 6 months and a mineral booster can be added if necessary for longer seasons or extreme conditions. The PoolRx method is proven to save money and time, while solving a variety of problems, and fulfilling the most common customer requests. Ideal for all of your chlorine pool, salt pool and spa customers.

What will PoolRx do?

  • Eliminates All Algae:
  • PoolRx will eliminate algae immediately and continuously for up to 6 months.
  • For extreme conditions or longer pool seasons you can add a PoolRx booster mineral tablet if needed.

How: PoolRx minerals dissolve out of the unit in the first 24 hours and form a stable residual throughout the entire body of water killing algae and bacteria. This frees up low levels of chlorine or salt chlorine to be more active and available. As the minerals pass back over the PoolRx unit during circulation, they are reenergized and last up to 6 months.

  • Reduces Chemical Demand:
    • 50% Reduction in your chlorine or salt chlorine demand.
    • 100% Eliminate need for harsh chemicals like phosphate removers, clarifiers, sodium bromide, etc.

How: PoolRx only requires 0.5-1.0ppm residual of chlorine or salt chlorine in the water to be completely effective. So you can start by putting in less. Second, the minerals are freeing up a low chlorine residual to become more active and available so it will take even less chlorine to reach your desired ppm.

  • Simplifies Pool Maintenance:
    • No installation required.

How: Start with a clean filter and simply drop PoolRx unit into the skimmer or pump basket, maintain normal pool chemistry, and as little as 0.5-1.0ppm of chlorine or salt chlorine. Do not re-clean or backwash filter for at least 2 weeks so minerals can dissolve through filter.

  • PoolRx minerals last for up to 6 months.
    • Minerals are lost through algae and bacteria kill, splash out, filter cleaning and back washing
  • For longer seasons or extreme conditions, a PoolRx Booster (pn.102001)can be added if needed
    • Mineral Booster should be added to skimmer or pump basket to dissolve. Not inside of unit
    • Leave original PoolRx unit, now empty, in either basket so it can rejuvenate booster minerals
    • Start with New PoolRx unit at the beginning of each season
      • PoolRx unit is effective in rejuvenating minerals for up to 12 months in the water and needs to be replaced every year
  • Reduces Energy

How: PoolRx is so effective you may be able to turn down the circulation pump run times, saving you money on your monthly electricity bill. With the PoolRx method you only need to turn water over once in 24 hours.

  • Prolongs the Life of your Equipment and Surfaces

  • Ideal for Salt Cells-Improve water quality- prolong life of salt cell

How: With PoolRx in the water, you can turn down Salt Generator by 50%. Thus, also reducing the acid needed to balance the water. The mineral formulation includes a natural de-scaler that helps keep the cell cleaner, longer, reducing frequency of cleaning. With PoolRx there is no need for other harsh chemicals. All of these factors improve the quality of water, while prolonging the life of the salt cell and reducing scale build up on surfaces and equipment.

  • Replace the need for a Salt Pool

How: A PoolRx Mineral Technology Pool is even better than a Salt Pool. The minerals work with a very low chlorine residual and no other harsh chemicals to provide amazing water that is easy to maintain. PoolRx and 1-2 tabs per week. Add a mineral booster in 4-6 months if needed. Start with a new PoolRx unit at the beginning of every season.

  • Prolongs ‘Water Life’

How: 50% less Chlorine means 50% less Cyanuric Acid (CYA) build up, (if you are using tabs). With PoolRx you can 100% eliminate the need for other harsh chemicals. Less total chemicals means lower TDS (Total dissolved solids) Lower CYA and TDS means water does not get OLD?é¼?¥ as quickly. It will now take less minerals and chlorine to be effective for a longer period of time. With PoolRx it will require less frequent drain/refills?é¼?¥ of pool.
