What is a sequestering agent for swimming pools?

Sequestering Agents are chemicals used to bind-up minerals and metals in solution, making it difficult for them to precipitate out of solution to cloud the water or stain the pool. They do not actually remove metals from the water, but keep them ‘sequestered’ or locked in solution with tight chemical bonds.

How long can a plaster pool be exposed without water?

eight to ten days
If the pool ever needs to be drained to replace the water or to maintain the plaster, it should never be left empty for more than eight to ten days at the most. More than this may cause the plaster to dry out and crack.

How long can a Pebble Tec pool be empty?

DO allow time (approx. 28 days) before assessing your final water and finish colors. The start-up and balance will allow the water and finish color to change over this time period.

Is it OK to leave Pebble Tec pool empty?

You should never enter an empty pool. We recommend that you wait until the pool is completely finished, filled and that the water is chemically balanced to start enjoying it.

When to add sequestering agent to plaster pool?

Although optional, it is highly recommended to pre-dilute and add a quality sequestering agent using the recommended initial start-up dosage and then the recommended maintenance dosage per the sequestering agent’s manufacturer. This is cheap insurance against metal staining. Operate filtration system continuously for a minimum of 72 hours.

How are phosphate reducers and enzymes in pool maintenance?

Phosphate reducers and enzymes can be an important part of pool maintenance. By John Weber. By Nick Orabovic Enzyme Time Enzymes are proteins that act as catalysts, speeding up chemical reactions. The substance on which the enzyme is reacting is called a substrate, which fits neatly into an enzyme.

Can a synthetic enzyme be used in a pool?

Enzymes by their very nature are produced by natural things and are therefore themselves natural. Synthetic enzymes are substances which are not enzymes yet mimic their activity. Since they are not actually enzymes, they cannot be labeled as such and none are known to be used in the pool and spa industry. All enzymes are alike.

Can a phosphate reducer be used as a sequestrant?

It should be noted that orthophosphates themselves are not useful as sequestrants. Despite the limitations, phosphate reducers can still be an effective tool for managing pools if used as part of a routine maintenance program. Since phosphates are so common in the pool, phosphate levels must be monitored diligently to ensure that they remain low.

How often should I add sequestering agent to my Pool?

Sequestering Agent weekly. Noted above) After the first 30 days, check the pool water routinely at least once a week or more often and keep the water balanced to the above noted water chemistry parameters. For Salt water pools: do not add salt to the pool for the first 30 days. Be sure to add pool acid weekly and lower the pH to 7.2 ppm.

How are sequestering agents used in water treatment?

In a nutshell, sequestering agents bind with the mineral (Fe, Mn, Ca, Mg) to keep them in suspension. This prohibits (delays) them from falling out and causing buildup, stains, discoloration, etc.

What makes a sequestering agent a chelating agent?

4. A sequestering or chelating agent is a complex forming auxiliary chemical with metals such as Iron, Copper, Nickel, Zinc and Magnesium that are present in water and affects the textile processing in many way.

What should the temperature be for a sequestering agent?

Testing should be performed to determine if they work. As a point of interest, we carry a sequestrant that will handle up to 7,000 ppm calcium/magnesium hardness at a treatment level of about 1-quart per 10,000 gallons, and is temperature stable to about 140F.
