I have a 15,000 gallon, in ground, plaster, salt water pool with cartridge filter. It has iron staining from well water used to fill it. About 5 years ago I treated the stain with the Jacks Magic products and it worked well. However over time I stopped adding the sequestrant and the stains slowly returned but not as bad. I now only use water that comes from the softened water that gets most of the iron out for the house. So I decided to try and address the stains again and decided to try the Metal Magic product after emailing someone at the company. I did there sponge test and it removed the stains. We decided on 3 quarts for the pool and I followed the instructions and it did lighten some of the stains but did not completely remove them. Now I am wondering if I should try the absorbic acid treatment now to see if that will remove all of the stains. If I understand it correctly the Metal Magic is also a sequestreant. Would adding the AA to it now be a good idea? Would it require additional sequestreant? Just trying to figure out what to do next. Thanks
