Experiences with swimming pool copper ionizers?

I used to sell/install them. Probably did over 50 pools. They do work. May not totally rid you of chlorine but will cut usage by 80% or more. Key thing is to maintain water balance (ph and alkalitnity/hardness) and monitor copper levels weekly.

Do they work? Yes and no. You need to be extremely careful checking the copper level or you will stain the hell out of your pool surface. Oh and green hair, green stained swimsuits, etc...

If your looking to reduce chemicals, look into the salt systems, they use electrolysis and salt to produce chlorine. The difference from using salt vs pool chlorine is that the salt/electrolysis process doesn't form as much Chloramines, which irritates the eyes and give pools that "chlorine" smell.

Great systems

Not that you asked but I have a UV/Ozone system on my pool and love it.

A lot of the pool companies in BR are getting away from salt systems fwiw.

This is not true. All the salt systems do is manufacture clorine ions from the salt. So, you get all the things that come along with chlorine -- the smell, the eyes, etc.

Copper is amazing at inhibiting algae and definitely cuts your need for chlorine -- salt-generated or regular. I find it easier just to buy copper algaecide and put 2 oz's per week in the pool. It's cheap, works like a champ, and no equipment to buy and maintain.

I started using pool RX a few months ago. Can't tell if it was worth the money but it wasn't expensive.

Not familiar with that brand, but they are fairly simple devices beyong the electronics. OP is right, need to monitor copper level weekly - too much can cause staining issues with blond hair (ask how I know) or gunite lining. Never had one stain a pool tho. I sold the Caribbean Clear brand which also had silver in the electrodes for bacteria. Electrodes usually lasted 1-3 years depending on size of pool and usage.

Now they are saying go back to chlorine if you salt. Salt destroys the shite out of everything.

When it's time to replace, go chlorine.

I have salt/gunnite and have done nothing but add a few bags of salt a year...that's it.
