The silver and copper act together as a biocide, with silver oxide as the sanitizer and copper working as an algaecide.
A great alternative to heavy chemicals silver and copper ion mineral sticks reduces bromine and chlorine usage by up to 50% in most spas, without high levels of chlorine or bromine-low maintenance. 
Most mineral sticks are replaced every 4 months, when the silver and copper depletes. No other equipment involved, so no other maintenance is needed.
