PoolRx Spa Mineral Cartridge

The cartridge contains a specialized mineral blend that dissolves into your spa water over time. These minerals create a residual effect that actively prevents algae growth and helps sanitize the water, allowing you to use fewer harsh chemicals like chlorine or bromine.

This specific cartridge is calibrated for spas between 400 and 1000 gallons. If your spa is outside this range, the mineral concentration will be either too diluted to be effective or too concentrated, which could potentially cause water balance issues.

No, it does not replace your sanitizer entirely. While the PoolRx cartridge significantly reduces the amount of chemicals you need to add, you still need to maintain a low level of sanitizer to ensure the water remains safe and bacteria-free.

Installation is straightforward. You simply place the cartridge into your spa's filter basket or directly into the filter housing where water flow is consistent. Once it is submerged, the minerals will begin to release automatically.

The lifespan of the cartridge depends on your specific usage, water chemistry, and filtration habits, but it is generally designed to last up to six months. You should monitor your water clarity and algae prevention to determine when it is time for a replacement.
