Mold inhibitor for liquid cooling system

[max384]

Hey guys, I'm building a keezer that is liquid cooled. Basically, I just have a bucket of water in my keezer with a pond pump that circulates the cold water around the shanks via copper tubing. I am not using glycol because my bucket of water is not below freezing and there is better heat transfer in water vs a glycol mix.

My build thread is in my signature if you need pics/description of the build.

My question is, is there any liquid mold inhibitor I can add to the circulating water? I'm afraid that if I just have tap water running through it and sitting in a bucket that mold will eventually form. Does anyone have any recommendations? Should I just use pool chemicals?

Distilled water and star san?

Distilled water and star san?

My concern with Star San is how the continued exposure to the acidic solution will affect the pump. I accidentally left some kegging hardware in Star San for a week, and they were severely corroded.

Copper and silver are both natural antibacterials in water. If the copper in the chiller isn't enough, perhaps a gram or two of copper sulphate pentahydrate.
