It was my understanding that using mercathode and having magnesium anodes cancel each other out by both over protecting. While using mercathode, you need to use aluminum anodes. This might be the source of your problem.

Not correct, different metals have different properties and do effect current

Do you have a galvanic isolator installed? You should.
if you have a pro sport charger, you can ground the chassis of the charger. Talk to their tech support, there was a known issue where that charger could contribute to the problem.
