Eliminate unsightly metal discoloration from your pool or spa with the Bio-Dex Aquadex 50 Stain-Off ADQ50, a concentrated 32 oz treatment engineered to lift copper, iron, and black cobalt stains from plaster and fiberglass surfaces. Its chemically stable composition retains full potency even at elevated temperatures, making it an excellent choice for heated spas. Chlorine, acids, and other sanitizing compounds do not diminish its stain-fighting ability, so you can treat without disrupting your normal chemical routine. Visible improvement typically appears within 48 hours to 10 days depending on how old and deep-set the staining is. Stubborn marks may warrant a follow-up application after the initial 10-day period. For especially resistant metal stains during an acid wash, Aquadex 50 Stain-Off pairs effectively with Plaster White 'n Brite as a supplemental booster. Incorporating this product into your regular maintenance schedule helps ward off future metal stains and preserves the clean, polished look of your pool or spa interior.

Installation & Operation Tips

Pour Aquadex 50 Stain-Off directly into the water at the location where staining is present. Swimming may resume after a 30-minute waiting period. The formula maintains its stability regardless of water temperature. Keep in mind that stain removal is a gradual process, and deeply set stains may need an additional round of treatment. Operate the filter frequently and allow up to 10 days for complete results. For optimal performance, target a lower pH of 7.2 rather than 7.8.
