PoolRx+ Pool Unit:

PoolRx+ contains a proprietary blend of minerals that continuously and effectively eliminate algae. The specially treated alloy cylinder is packed with PoolRx+ granular 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 pool’s 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.

Also Ideal for Salt Pools:

PoolRx+ improves the saltwater experience. The minerals reduce the salt chlorine production needed to keep your salt pool 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.

Directions for use:

It is a violation of Federal Law to use this product in a manner inconsistent with its labeling.
• Clean or backwash your filter before adding PoolRx and remove all debris from skimmer andpump basket.
• Place the PoolRx+ pool unit into Pump Basket or Skimmer. Ideally place in pump basket for increasedwater flow.
• The PoolRx+ pool unit should be added to the pool when the pump has at least 3 to 4 hours left on runcycle. This will ensure the granular completely dissolves out of the unit and through the filter into the pool.
• Pump should run during the heat of the day.
• Your pool should turn over its total volume of water at least 1.5 times per day. Generally, this will require 6 to 8 hours of pump runtime depending on gallons of water and pump flow rate. Do not re-clean or backwash filter for at least 2 weeks after PoolRx+ pool unit is installed so granular can dissolve through the filter, whether it is a cartridge, D.E. or sand filter.

Replace the PoolRx+ unit in the basket every 12 months. Add a PoolRx+ booster after 4-6 months if needed. If you see algae is coming back or the water looks a little dull, you know it's time to replace these lost granular with the PoolRx+ booster (Part #332001). Start with a new PoolRx+ Pool Unit at the beginning of each season.

No need for phosphate removers, other algaecides, clarifiers. PoolRx+ pool unit is not compatible for use with bromine or biguanides. Do not add calcium hypochlorite (Cal-Hypo) products directly to your pool. Cal-Hypo products must be diluted prior to adding to your pool.

Before draining a treated pool contact your local sanitary sewer and storm drain authorities and follow their discharge instructions. Do not discharge treated pool or spa water to any location that flows to a gutter, storm drain or natural water body unless discharge is allowed by state and local authorities.

    It’s the best thing I’ve ever seen for a pool. I have a salt system but last year I had a ton of problems with black & green algae. I don’t close my pool for off season. I installed it in October & haven’t a a single problem and pool is crystal clear & blue. 04/2023

    Pool looks cleaner and brighter

    I have used Pool RX for about 10(?) years now. I absolutely love it. Opening, clean pooled chlorine as needed, once clean and balanced, drop in the Pool RX cartridge and forget it! Works as it says it does. May chlorine levels are so low, they barely register on a test strip. I highly recommend this product.

    Game changer. Kept pool clear and clean. Even over winter. I will never go without it! It works great!

    Grandkids commented after I installed without even telling them how clear the water is . Noticeably clearer than usual

    I ordered the 30k gallon one and you sent me the 20k. Don’t see much difference

    I bought PoolRx+ Blue/White (with silver). It did not come with instructions, so I relied on your website. It says “During the pool’s filtration process the minerals are rejuvenated every time they return and pass through the cylinder”. That sounds like I should leave its cage in the basket. There are no instructions like this. If it is true, you owe this information to all buyers.

    The blue one wasn’t on the site when I purchased and I purchased the black one. A little more expensive but absolutely an amazing product. I am a customer for life now. Thank you. Very happy.

    For years my pool service was adding chemicals at $100’s with multiple applications to fight algae, without success. Then my pool service recommended PoolRX. I’m now into my second year of use because this stuff works! Great price point and it works!

    I was having trouble with algae and tries everything but nothing worked. My pool was a bluish green color. We use the all blue Pool RX last year but when i took it out i did bot replace it. My wife told me to go buy another Pool RX and try it. I was very skeptical but bought one and installed it around 5:00 in the afternoon. The next day at 10:00 in the morning my pool was almost back to normal. Water was clear and algae was gone. I was amazed and this product is amazing. I used the blue & white Pool RX. It is amazing and makes pool maintenance simple.
