I could use some expert opinion on a project I was asked to work on. The project is a show at a theme park involving a show with multiple dynamics ideal for having (and it does) corrosion problems. The show is using a 500,000 gallon tank filled with potable water. There are several different metals in the mix. Steel, stainless steel, bronze, copper and cast iron. There is a tremendous amount of underwater lighting also, however I do not yet know if it is 110v or 12v.

The water chemistry is similar to a swimming pool and the system maintains a low chlorine residual of 0.5 ppm and the TDS or total dissolved solids measure 300ppm. The steel plate of the boat hull is pitting as well as the track that it runs on .

Okay,, yes I have a question.

1. sacrificial anode or cathodic protection ?
2. with such low conductivity, the spacing or placement of anodes
