Pool & Spa

Calcium (Scale)

Scale found in pools and spas, is usually characterized as that ugly and rough, chalk-like build up that often occurs along the waterline. This can be visible on beautiful water features, or may even cover the entire surface in a sand paper-like crust. Scale is not only unpleasant to look at, but can also make surfaces rough to the point of being dangerous. Scale can also contribute to many other negative factors that impact the overall wellness of the water. Scale (calcium carbonate) has been an ongoing problem in many pools and spas due to the fact that over time minerals precipitate (fall out of solution) and settle, becoming a solid on the surfaces. There are many different situations that can cause this process to take place, but the most common is when the water has a high calcium hardness level. Quite often the first sign of problems is clouding water. This is not just an unsightly problem. Calcium carbonate can cause skin abrasions, snagged bathing suits, and can clog filters. When scale builds up in piping, circulation is reduced and pressure increases. Calcium carbonate has been recognized in the pool and spa industry for years, however, recently another type of calcium has become more common- calcium phosphate. This form of scale is created when phosphates combine with calcium in pool and spa water, particularly in heated water. This combination is an insoluble white scale that is complex and very difficult to remove. When calcium phosphate falls out of solution, it can often resemble DE or sand, feel gritty to the touch, and often gathers at the bottom of the pool or spa. When it comes to any type of scale whether it is calcium carbonate or calcium phosphate, prevention is best. Scale is difficult to remove once formulated. Plan to use a PHOSPHATE FREE stain & scale product such as Natural Chemistry’s SCALEfree for pools or Spa Stain & Scale for spas and maintain phosphate levels below 100ppb, to help prevent scale accumulation. This is especially important for new plaster finishes, and pools using a salt generator system.

Spa Stain & Scale

Spa Stain and Scale protects spas from the damaging effects of scale buildup and staining due to excessive calcium, iron, copper and other minerals. It works without the use of phosphates or harsh acids. Spa Stain and Scale also works to prevent scale from forming on salt generator cells to help maintain optimum performance. Note: This product can be used with most sanitizing systems and is compatible with all spa surfaces. Do not use with biguanides.

Spa Foundation

Spa Foundation has been specifically engineered for all spas and hot tubs. This easy to use multi-mineral product has an amazing impact on water quality and is effective at reducing and maintaining low levels of phosphates. When combined with the other products in Natural Chemistry's Perfect Spa Program, maintenance is a breeze!

PHOSfree

Reducing phosphate levels in pools is easy with Natural Chemistry's patented PHOSfree technology. PHOSfree is formulated from lanthanum (rare earth) compounds. When added to the skimmer, a thin coating of PHOSfree forms on the filter media. As pool water flows through the filter, phosphates are reduced to a very low level.

SCALEfree also works to prevent scale from forming on salt generator cells, helping to maintain optimum performance. SCALEfree can be used with most sanitizing systems and is compatible with all pool surfaces.
