Metal Staining

Surface Staining

To remove organic stains chlorine should do it. If you have just a few spots rub chlorine on them and they will go away. If you have more contact a professional to remove properly while keeping your water balanced. Water balance or water chemistry is the most important aspect of keeping your pool water safe and beautiful.

Or if you see an all over kind of greying occurring to walls of pool that is also metal staining.

Metals in the water come from a plethora of sources:

Well water, bad city water, salt systems, copper gutters, brick, brick pavers, stones by the pool, plants by the pool, fertilizer, water run-off (rain), irrigation water, fire features, fireworks, water features with faux stone or real stone, gas heaters, old copper pipes, algaecide, chlorine tabs (those blue flecks are copper), leaves, water hose with copper fittings, etc.

The CULATOR.COM website has a lot of education on metal staining and products that can help remove metal stains and maintenance product that is placed in the skimmer. Any Leslie’s has their products as well.

Removal:

• Have the pool water analyzed. This is key in determining what is off in the water balance to allow metals to adhere to the walls of the pool.
• Treat your pool with a metal eliminator. Jacks Magic or CULator Ultra 4.0 should remove the stains BUT now the metal is back in your water.
• Remove metals from your water. Jacks Magenta will remove the metals from the water.
• Add Chlorine back slowly. Adding too much chlorine back too fast can cause stains to return.
• Perform accurate pool water maintenance. Have your water tested (analyzed) to keep water in balance, so stains do not return. Use of a sequestering agent will help block metals from staining.
• If stains come back consider: bonding the pool. Ask your installer for a bonding kit and have it installed by a professional.

Good water chemistry can only be achieved when all four of the chemical levels are kept constant. Good Alkalinity helps keep the pH in the right range so that chlorine can do its job properly. Stabilizer (cyanuric acid) keeps more of the chlorine in the water instead of it being wasted = crystal clear pool.

Regular testing (analyzing) of pool water is a critical part of any maintenance routine.

Below are the ideal ranges to keep your pool Safe, Comfortable and Crystal Clear.

Five Errors Commonly Made

One – Not running filter long enough for it to do its job and filter maintenance – clean it or back wash it.

Two – keeping pH within ideal limits

Three – Support products such as boride, enzymes and sequestering agents to help maintain the pool water

Four – Leaves and acorns can cause havoc on water balance

Five – Using well water without balancing water chemistry or using sequestering agents
