I am lowering my chlorine, adding polyquat and am about to add ascorbic acid. Have any of you guys tried a product like CuLator power packs ( from pinch a penny) You put them in them in the skimmer and the iron in the water collects in the bag. Do they actually work? Does it remove iron that is sequestered? I have a pinch a penny here in town- which sequestering agent should I use after the ascorbic acid?
