Considering reinstalling my AquaTrol on our new-to-me Aqua Leader 18x36x52 pool, but am apprehensive b/c of the inner wall rusting issues it did to my last round pool. I think it was an uncommon occurrence, but am looking for others opinions. Also, if I do use it, I'm considering painting or cold galvanizing the top metal plates, to prevent rusting. I will use SS/galvanized fasteners on the deck and use only plastic seating. Any feedback would be great!
