Pool Flocculant Not Working

It is important to note that aluminum flocs only work at a high pH so you must first raise the pH of the pool to at least 8 when using Alum or 7.8 when using a liquid PAC-based product. Alum has a low pH and will immediately reduce the pH of the water after addition.

A common practice when using Alum is to raise the pH to 8+ using Soda Ash and then add 2 to 4 kg of sodium bicarb (buffer) at the same time as adding the Alum. This will compensate for any drop in pH and also increase the Total Alkalinity. (PAC) Poly Aluminium Chloride is a kind of inorganic polymer, which is made from the reaction of aluminum mineral powder and hydrochloric acid.

Here’s a list of potential reasons why the pool flocculant may not be working as expected:

Incorrect Dosage:

• Under-dosing or over-dosing the flocculant can result in ineffective treatment.

Poor Circulation:

• Inadequate water circulation prevents the even distribution of flocculant throughout the pool, leading to incomplete treatment.

Unbalanced Water Chemistry:

• Imbalanced pH, alkalinity, or sanitizer levels can hinder the effectiveness of flocculants.

Presence of Algae or Organic Debris:

• Algae bloom or excessive organic matter can interfere with flocculant action and contribute to cloudy water.

Filter Issues:

• Clogged or malfunctioning pool filters may not effectively capture the clumped particles, reducing the effectiveness of the flocculant.

Insufficient Filtration Time:

• Not allowing enough time for the flocculant to work and the particles to settle before turning on the filter can impede clarification.

Water Temperature:

• Extremely cold water temperatures can slow down the flocculation process, delaying visible results.

Quality of Flocculant:

• Using expired or low-quality flocculant may result in subpar performance.

Pool Size and Volume:

• Using the incorrect dosage relative to the size and volume of the pool can impact the effectiveness of the flocculant.

Water Quality:

• High levels of dissolved minerals or other contaminants in the water may interfere with flocculant effectiveness.

Addressing these potential issues can help troubleshoot why pool flocculant isn’t working and guide towards appropriate solutions for achieving clear, clean water.

You need to shock your pool with chlorine first to kill algae, the most commonly used disinfectant and oxidizer for pool water. Once the chlorine kills and leaves dead cells in the water the flocculant can clump them together and settle them out to the bottom of the pool where you can vacuum them out. You didn’t wait long enough- On the back of the Flocculant is a dozing recommendation and a wait time. You need to follow the directions because each product could have different doses and different wait times.

If your application of flocculant didn’t work the solution might be as easy as wait time. Read the label and directions on all chemicals including pool flocculants, The cloudiness in the pool could be caused by an imbalance in water chemistry Pool flocculants are made to physically remove debris from your pool by settling them out and then physically vacuuming them removing them from the pool completely.

If there is a balance in the pool water such as TA (Total Alkalinity) then these Balance issues are the underlying problem and the Flocculant will never clear your pool water. The solution is always to test pool water chemistry first and then adjust the chemistry of the pool water before adding shock chlorine to kill the algae and organic contaminates-followed by adding the correct and recommended amount of flocculant according to the directions on the package to settle out the dead algae to the bottom of the pool to vacuum.

How Flocculants Work to Clarify Pool Water

Pool flocculants operate on the principle of coagulation and precipitation. When added to the pool water, flocculants introduce positively charged ions that neutralize the negative charges on suspended particles, such as dirt, dust, and algae. This neutralization causes the particles to attract one another and form larger, denser clumps, known as flocs.

As these flocs grow in size, they become too heavy to remain suspended in the water and gradually sink to the bottom of the pool or rise to the surface, where they can be easily removed through vacuuming or skimming. By facilitating the aggregation of tiny particles into larger masses, flocculants enhance the efficiency of the pool’s filtration system, resulting in clearer water.

Different Types of Pool Flocculants Available and Their Mechanisms of Action:

Inorganic Flocculants:

• Inorganic flocculants, such as aluminum sulfate (alum) and aluminum chloride, work by forming insoluble compounds with suspended particles, causing them to clump together and settle out of the water.

Organic Polymer Flocculants:

• Organic polymer flocculants, including polyacrylamide and polyDADMAC (polydiallyldimethylammonium chloride), function by binding to suspended particles and forming larger aggregates that are easily filtered out.

Combination Products:

• Some pool flocculants combine both inorganic and organic components to maximize effectiveness. These hybrid products often provide a synergistic effect, enhancing particle aggregation and sedimentation.

Liquid vs. Granular Formulations:

• Pool flocculants are available in both liquid and granular forms. Liquid flocculants are typically easier to apply and distribute evenly throughout the pool water, while granular flocculants may require pre-dissolving before use but can be more convenient for certain applications.

Understanding the different types of pool flocculants and their mechanisms of action empowers pool owners to select the most suitable product for their specific needs and effectively clarify their pool water for a clean and inviting swimming environment.
