Pool Stain Gallery

These are pool and spa stain and water discolor images.  These may help you decide what type of metal stain you have on your gunite, fiberglass, or vinyl sided pool.  All images were sent in by CuLator Metal Eliminator customers.  Some pool stains are organic in nature, but these stains and discoloration are all caused by metals in the pool and spa water.


How Do Metals Get Into Pool And Spa Water Gallery

Metals are naturally occurring substances found everywhere, including stone, soil and water. Rainwater is acidic and tends to dissolve the metals found in soil and stone, thereby increasing metal concentrations in surface and ground water. Furthermore, because all municipal and well water contains some metal, introducing metals into your pool is unavoidable. Galvanic corrosion, especially in salt water pools, and irrigation (reclaimed well water) are also common sources of metal contamination.
Additionally, stone water features, decking materials, plaster pool surfaces, pool chemicals, pool equipment, and lawn fertilizers are all potential sources of metal contamination. Marble, flagstone and granite, for example, naturally contain iron, which can leach into a pool after every rain. Salt used in all salt water systems also contains iron. Copper can be introduced into pool water from the heat exchanger found in the pool heater, from copper-based algaecides, or from mineral-based water purification systems. Manganese and nickel, also commonly found in pool water, are frequently in the source water used to fill pools.

All of these issue can be controlled with different combinations of sequestering agents, CuLator Metal Eliminator and Stain Preventer, and the No-Drain Metal Stain Eliminator Kit.
