Backyard Pools Safe for Pets? – Ask Annie
I asked my friend Mick for the answer, as he has had many koi pools over the years, and here is what he suggests: “One thing that I have done with my small ponds in the past is throw a bunch of pre-1980 (100% copper) pennies in where there is a lot of water movement. The copper oxidizes and helps to control algae.” He also uses Oxy-Boost for periodic “shock” treatments.
