Hi everyone I have a quick question for you…Can you use sacrificial zinc anodes in a surge tank to help prevent corrosion without affecting the chemistry of the pool? We have valves in our surge tanks that are cast iron. They are old, however we are trying to prolong the life of them and have recently came up with this idea. There is little on the web about using them in a pool environment, and I know you can actually sanitize the water through zinc, however I just don’t want it messing everything else up.
We use cal hypo as the sanitizer, cyanuric acid as stabilizer, and hydrochloric acid to balance.
