The Truth About PoolRx and Copper
PoolRx is a small mineral unit that sits right in your pump basket. As water flows past it, it slowly releases copper into the pool, and copper is a natural algae fighter.
What it does well: it keeps algae from getting a foothold, so a lot of pools can run a little less chlorine day to day and still stay clear between visits.
The Honest Tradeoff
The copper does not leave with the water. Unit after unit, season after season, the copper level quietly creeps up, and nothing takes it back out. Let it climb too high and copper can stain light plaster a blue-green color, and it is the classic reason blonde hair picks up a green tint after a swim.
PoolRx is a helper, not a replacement. It does not brush your walls, balance your water, or clean your filter. The weekly basics still do the heavy lifting.
Used right, it is a genuinely good tool. Just test the copper a few times a season and let that reading, not the calendar, tell you when it is time for another unit.
