Baquacil reacts with iron in the same way that a swimming pool reacts with chlorine. The water usually turns brown or green, and the product that cleans it is Baquacil Metal Control, which filters it. It is best to check the filter during this time and hose it out if necessary as the filter will look like it has rust in it.
I can’t answer your specific question about iron – but given baquacil’s other properties like “eats plastic”, “results in what is known as pink slime”, I wouldn’t be surprised if the reaction was “bad”. Taken? You can say that but trust me I have never seen a baqucil pool with truly clean water and I have spoken to many pool owners who have grown to hate this product, its performance and price.
