No. Copper and silver both need to be at levels right around the levels where staining occurs to be effective. Even then they are only effective against algae, and not sufficiently effective against viruses and bacteria. In the US public pools are required to have residual levels of a listed sanitizer. Neither copper or silver is a listed sanitizer. Nor will adding chlorine once ever two weeks provide a suitable residual level. Following their directions will result in a pool that is not safe and as a result using their system as described in a public pool is illegal.
On top of that, the levels of copper/silver required to be effective are also the same levels that will cause dramatic and difficult/expensive to remove stains on the pool if you are not exceedingly careful to maintain the PH at low levels. PH tends to rise on it's own, so it doesn't take much lack of attention before staining starts.
By the time you have a suitable residual level of sanitizer in the water, that alone takes care of everything you need (for a residential pool). There isn't any point in adding copper/silver as it provides no additional benefit, costs extra, and runs the risk of staining.
