Could copper disinfection in a swimming pool be harmful to swimmers?

the website intec-america.com is selling copper disinfection systems for swimming pools and I am worried that swimming in copper can absorb through skin and be harmful. I wonder how long they've been in business selling them.

I would stay far away, I don't know how long intec has been selling it or what effect it has on skin, actually all of my online research indicates that no one knows what it does to your skin, though copper levels in your body that are out of balance can cause premature heart failure, but copper can also destroy a pool... First of all when copper oxidizes it turns green, no one wants to swim in a green pool. Copper oxidation accelerates in a pool due to chlorine and low or high ph. This oxidized copper causes green stains on blonde hair, and green stains on the plaster layer of gunite pools. Your water will have to remain perfectly balanced in order to prevent damaging copper oxidation... and it still might happen. You will then have to chelate the water to remove it (expensive). You may even have to drain and refill which may cause your plaster to chip off. If it stained the walls green an acid wash might fix it... but if it doesn't you have to re-plaster or live with green stains. re-plastering starts at 2000 dollars and takes forever. I've personally serviced a few of these copper systems. They still get algae, they still need a secondary sanitizer, they're initial cost is high, and they can destroy your pool. My advice no matter what you've heard is a salt system. Salt pools are in fact chlorine pools, but the chlorine is regenerative. You will save a significant amount of money over the life of your pool, all without handling dangerous chlorine directly. Your tap water probably contains as much chlorine as is required to disinfect a swimming pool. So go for chlorine without ionization... or better yet saltwater chlorine.
