I will be using 34% H2O2 and pH down acids and GH nutes in the res. Will there be any negative effect on the coil of copper/steel. I would like to know which metal would be best to make a wort chiller(well its a reservoir chiller now). copper or stainless steel. Any information will be greatly appreciated. I have researched it for hours and all I can do is repeat chemical stuff I know nothing about. Thanks in advance.
