    I have been fighting an algae problem with my pool this summer. It's not the first time but it got started early and I could tell it was going to be bad. So there's this device that came on the market a while ago, it's called "Pool Rx."

    I avoided buying it previously as it apparently works by substituting Cu and Ag ions into the water in place of some other ions, and I couldn't find much info it and I didn't know how safe it was.

    Well, I went ahead and put it in the skimmer basket and within 48 hours all of the algae was gone. It's been a week now and it not only cleared up my algae problem but the little bit of athlete's foot that was between my little toes!

    So, apparently algae, fungus and who knows what else can't survive in the presence of Ag and Cu ions.

    Any thoughts on the chemistry of this?

    I can tell you that silver has some pretty significant antibacterial/antifungal properties, but I'm not sure about silver ions in solution.

    I remember adding like silver nitrate or something to HCl (I think) to precipitate AgCl out (You're either part of the solution or part of the precipitate).

    But there was none precipitated out with the addition of the Pool Rx to my pool - and it had plenty of chlorine in it! So I don't know what gives.

    You wold not be able to see it as a cloud or a distinct precipitate , you only have it in there at ppm levels.
