Staining on your pool surfaces are commonly caused by high levels of metals in your pool water. Unbalanced water, high pH levels or shocking the pool can cause these metals to oxidize or “plate out”, staining your pool surfaces, clothes and even your hair. Traditionally the pool would have to be drained and the stains treated by a pool professional. Thanks to our No Drain Metal Stain Eliminator Kit, you can do-it-yourself without having to drain the pool, costing you valuable time and money in the process.
