PoolRx+ Booster:

The PoolRx+ booster contains the additional minerals needed to replace minerals that are lost through back wash, splash out and algae kill. PoolRx+ booster can also be used for larger pools that need additional minerals when initially installing a PoolRx unit. These minerals do not need to go back into the PoolRx unit; they just need to dissolve back into the pool water. These minerals generally need to be replaces every 4 – 6 months, depending on your swim conditions.

Directions for use:

It is a violation of Federal Law to use this product in a manner inconsistent with its labeling.
•Clean and backwash the filter and remove all debris from skimmer and pump basket before adding the PoolRx+ booster, you do not want the minerals to get stuck on the dirt and then backwashed out.
• Add 8 ounces of booster mineral per 7.5k – 20k gal into the skimmer or pump basket. Do not remove the existing PoolRx unit. The minerals will start dissolving immediately. Make sure there is at least 3 – 4 hours of the pump run cycle. This will ensure the minerals completely dissolve without getting caught up in the filter
• Pump should run during the heat of the day
• The pool should turn over its volume of water at least 1.5 times per day, this normally requires 6 to 8 hours per day this depends on gallons of your pool and pump flow rate.
• Do not re-clean or backwash filter for at least 2 weeks so minerals can dissolve through the filter whether it is a cartridge, D.E. or sand filter

    I started using the PollRx black/white last year and it has done an amzing job of keeping my chemicals balanced and my chlohrine and PH levels stable.
