Hey guys, I've been doing some research on this topic and I would like to ask for your opinion.

I'm wondering if Cu-ETP copper alloy is a good option for pool water treatment using ionization.

The purity of this copper alloy is 99.5%, with the remaining amount being phosphorus and a little bit of oxygen.

I already have an ionization system installed, but now I need to replace the electrodes.

I'm trying to find a better deal by speaking directly with the metal supplier instead of paying over 250 euros for 1.7 kg of copper from the ionization system manufacturer. Which I find very overpriced for 6 copper electrode pieces of 18mm diameter by 100mm long.

As of my research, the most used copper alloys are:

• 85% Cu+15% Zn (brass);

• 99.5% pure copper;

• 94% Cu + 6% Ag;

• 67% Cu + 33% Ag;

Any advice would be greatly appreciated.

Thanks in advance.

Copper is very expensive! Copper is also very maleable. If it were me, I would try to make my own electrodes from copper pipe or copper rod. I recently purchased graphite rods to make electrodes but haven't tried them yet. This forum is not geared to such questions so the experts may be elsewhere.
