Questions and Answers

Crystalplus system is a tested and approved product that was introduced on the market to fill a gap which currently available products have not been able to fill. Interviews with thousands of pool owners have allowed us to determine that problems occur during heat waves, among them: algae formation, instability in pH levels and questionable water clarity.

Crystalplus system works to fight off these problems by:

• Controlling algae
• Stabilizing pH levels
• Clarifying water
• Allowing you to use up to 50% less chlorine

All the ingredients that make up this tested and proven solution have been stabilized, calibrated and chosen specifically to:

• Reduce amount of chlorine traditionally required to maintain pool water.
• Eliminate the need for any other chemical product when treating pool water.

Crystalplus system is registered by Health Canada.

Yes. It is completely safe to use Crystalplus system in your Jacuzzi or Spa to improve water clarity.

You can start using Crystalplus system at any time during the season.

• Crystalplus system can also be used in water where many chemical products have been used or where high concentrations of chlorine exist.

Please refer to the "Easy to use" page for more details.

Crystalplus system is compatible will all types of chlorine, bromine, lithium and peroxide (active oxygen).

Crystalplus system is compatible will all types of chlorine.

On the market, you will find the following types of chlorine:

• Calcium hypochlorite
• Sodium hypochlorite
• Trichloro-s-triazinetrione
• Sodium dichloro-s-triazinetrione

1. Calcium hypochlorite
Calcium hypochlorite is composed of white granules and has a strong chlorine odour. Developed by OLIN in 1928, this manufacturing process has provided for producing concentrated chlorine. This process was called "High Test Hypochlorite". Nowadays, it is better known as its abbreviation, HTH.

• Active strength: 65%
• Available chlorine content: 65%
• pH: 11

Advantages:

• Easily handled
• No significant storage decomposition

Disadvantages:

• Raises pH
• Chlorine residual in pool dissipates rapidly in sunlight
• Can cause turbidity, scale, clogged filters if pH and/or T.A. are high

2. Sodium hypochlorite

Sodium hypochlorite is only stable as a solution. First produced in 1785 by bubbling chlorine gas into a solution of lye, in a chemical plant in Javel, France - hence the name "Javelle Water". Often called by the misnomer "liquid chlorine", it is sold under the brand Javex as laundry bleach. Pool chlorine bleach is double the strength of laundry bleach.

• Active strength: 10.8% (12% commercial)
• Available chlorine content: 10.3%
• pH: 13

Advantages:

• Completely miscible in water
• As bulk liquid it is the least expensive source of chlorine sanitizer except for gas chlorine

Disadvantages:

• Bulky and heavy to handle
• Bleaches clothes, carpets, etc.
• Raises pH
• Significant decomposition in storage
• High T.D.S.
• Chlorine residual in pool dissipates rapidly in sunlight

3. Trichloro-s-triazinetrione

Sometimes called "trichlor" for brevity, this white granular powder is formulated into tablets when used for swimming pool application. Trichlor is the most active of pool chlorines. This property should be respected from both usage and storage standpoints.

• Active strength: 100%
• Available chlorine content: 90%
• Stabilizer content: 56%
• pH: 2,8

Advantages:

• Easily handled
• Slow-dissolving
• Good for chlorinators
• Chlorine residual stabilized

Disadvantages:

• Reduces T.A.
• Lowers pH
• Readily supports combustion on contact

 
4. Sodium dichloro-s-triazinetrione
For brevity this white granular substance is called "dichlor" or "sodium dichlor". It is also sold in dehydrated form. Much as stabilized tablets, it is popular on residential markets and is sold in many different-sized containers, under many brand names.

• Active strength: 100%
• Available chlorine content: 62%
• Stabilizer content: 57%
• pH: 6.7

Advantages:

• Easily handled
• Fast-dissolving
• Little effect on pH
• Chlorine residual stabilized

Disadvantages:

• Most costly chlorine sanitizer

Specialists recommend you overchlorinate your pool regularly. Trichlor chlorine users can benefit from overchlorination as it can periodically reactivate the stabilizer found in the pool water.

When?

• Once a week.
• It is suggested that you overchlorinate following hot weather spells or overuse of the pool.
• Overchlorination does not affect the performance of Crystalplus system.

The following Health Canada document highlights the advantages of copper sulphate algicides for swimming pool use

• Control algae.
• Improve water clarity.
• Reduce the amount of chlorine or bromine-based products required.

They do not:

• Control micro-organisms such as bacteria and viruses.
• Eliminate the need for sanitizers such as chlorine or bromine-based pool products.

Crystalplus system contains 4% copper. The copper is efficient and safe when used appropriately.

No additional products are required except for chlorine or bromine.

Keep in mind that the pool water quality levels may fluctuate and need special treatments especially when weather conditions are extreme.

Yes, Crystalplus system is compatible with all types of water heaters and can be used safely in heated pool environments.
