Concentred metal sequesterent that helps remove and control unwanted dissolved metals from swimming pools and spas.
 
Benefits
  • Sequesters and removes metals from pool water by forming complexes (chelation).
  • Aides in scale removal and prevention
  • Regular use will prevent the deposit of new stains and continue to reduce older metallic stains
  • Excellent as a start-up for new and re-surfaced pools
Important Notes
  • This product will lower pH and total alkalinity
  • When readjusting, bring the pH and total alkalinity up very slowly.
Sizes
  • Quarts
Dosage

What happens when a pool interior stains?
All swimming pools interiors are made from chemical compounds of one type or another. Staining problems can start even before we commence filling the pool with water. Water is corrosive so it must be balanced by careful addition of certain chemicals. Added to this we must sanitize the water continually and re-check the balance to ensure the pool interior is not being attacked by the water itself and also to ensure that bathers are swimming in correctly treated water. Quite a mouthful, isn't it?
Staining occurs when insoluble chemical precipitates form in the pool. These may deposit on the pool interior and often they are hard to remove. For our purposes stains fall into two categories: Vegetable stains caused by falling leaves and other plant matter and metal stains caused by dissolved metals in the pool water.
 
Organic Stains
Spot dosing with granular chlorine is the easiest way to remove stains. Care should be taken not to bleach the pool surface, particularly when treating a patterned vinyl liner. It is suggested that the chlorine be suspended near the stain (use a synthetic sock or panty hose).
 
Metal Stains
This is a very complex subject. Metal stains are normally caused by dissolved iron or copper. Iron stains appear as a brown or rust colored discoloration. Copper stains appear as blue, gray or black discoloration.
 
Iron Staining
Occurs quite often in fibreglass pools. Traditional methods of treatment have included addition of various organic acids. These tend to alter the water balance significantly and may affect the chlorine reading on conventional test kits.
