I wasn't aware that silver was an algaecide. My advice would be to switch to a copper based algaecide. The cheapest is copper sulphate, but it is toxic and less effective in hard water where the copper immediately precipitates out as copper carbonate. There are chelated copper algaecides, like Cutrine, that are more stable and are suitable for potable water supplies. Unfortunately, the chelated products tend to be expensive. -- John A.
