Pool Spa Unit for 100-400 Gallons

The updated algaecide formula from Pool Rx, Pool Rx+, contains three active ingredients: Copper Sulphate, Zinc Sulfate, and Silver Nitrate. This addition of these three components provides extra layers of protection to the original Pool Rx formula that users have come to trust. The yellow Pool Rx+ spa unit is an EPA Registered, NSF/ANSI 50 Certified algaecide, supporting 100-400 gallons of water.

Pool Rx+ helps reduce chemical demand, improve water quality, and simplify spa care for up to 6 months. The re-treatment intervals, however, may vary based on factors such as bather load and splash out. It is recommended to replace the Pool Rx+ spa/hot tub unit each time the spa/hot tub is drained and refilled, or if algae is reappearing, or the water appears dull, even though the water is balanced and has at least 0.5-1.0 ppm of chlorine.

The Pool Rx+ products are designed to support any size body of water and are ideal for use in chlorine, salt, UV, or ozone spa/hot tubs. The new formula with its three active ingredients effectively eliminates all types of spa algae, reduces chemical demand, and is NSF/ANSI 50 Certified, ensuring its effectiveness and safety.

In summary, the updated Pool Rx+ formula offers enhanced protection, improved water quality, and simplified spa care for up to 6 months, making it a reliable choice for spa and hot tub owners.
