HTH

HTH treatment uses calcium hypochlorite as its active ingredient, an unstabilized chlorine formulation free of cyanuric acid. Unlike the trichlor or dichlor commonly available on the market, this compound disinfects without accumulating stabilizer residues in the pool water.

When cyanuric acid exceeds 75 ppm, it neutralizes the disinfectant’s oxidizing power, causing the water to become unresponsive and algae to proliferate. This product range offers clear operational advantages:

• Immediate oxidative disinfection with accelerated dissolution.
• Eliminates the risk of over-stabilization in the pool.
• Greater biocidal performance during periods of high pool use or storms.

To check the exact concentration of these parameters, it is recommended to use precise equipment such as the Lovibond MD200 3-in-1 photometer for chlorine, pH and cyanuric acid.

Granular HTH treatment is the right product for clearing green water saturated with excess cyanuric acid, without having to drain the pool completely. By providing unstabilized active chlorine, it oxidizes organic matter and neutralizes microalgae almost instantly.

The standard dosage for a shock treatment is 150 to 200 grams per 10 cubic meters of water, with filtration running continuously for at least 12 to 24 hours. Before applying the product, adjust the pH to a strict range of 7.2 to 7.4. This allows the bactericidal action to achieve maximum oxidizing performance and clarify the water without producing by-products that bother swimmers.

Calcium hypochlorite HTH must never be physically mixed with stabilized trichlor or dichlor in the same skimmer or dispenser. Direct contact between these substances causes a violent, exothermic chemical reaction and a dangerous release of chlorine gas.

To dispense slow-dissolving tablets without compromising the safety of the installation, use a separate device such as the Starpool 23 cm floating chlorine dispenser. If you decide to change the treatment system in your skimmer, thoroughly wash and rinse the basket to remove any traces of the previous product before adding the new one.

For a start-up chlorination of a 50-cubic-meter pool, exactly 750 to 1,000 grams of HTH granules are required. This calculation ensures that free chlorine rises above 5 ppm to inactivate any pathogens that may have remained dormant over the winter.

The technical application procedure consists of very specific steps:

• Dissolve the product beforehand in a bucket of clean water to prevent deposits on the bottom.
• Distribute the mixture evenly around the entire pool perimeter with the pump running.
• Use test reagents to check that residual chlorine levels have fallen to a safe range of 1 to 3 ppm before the first swim.

This procedure prevents discoloration of liner surfaces and protects the circulation pump.

Continued use of calcium hypochlorite formulations gradually increases the calcium hardness of pool water. For every 100 grams of product added to 10 cubic meters, hardness typically increases by approximately 7 to 8 ppm of calcium carbonate.

In areas with soft water, this addition is beneficial because it prevents corrosion of the joints, tile, and metal components of the filtration system. However, if the fill water already has a hardness level above 400 ppm, it’s advisable to monitor the balance regularly and alternate the product with lime sequestrants to prevent precipitation and whitish scale deposits along the waterline.

Multi-action tablets are effective in balanced water, but when accumulated stabilizer levels block the chlorine, the water loses its sparkle and becomes constantly cloudy. The HTH range solves this problem by providing pure available disinfectant that attacks microscopic particles in suspension without adding residual compounds.

When you add this unstabilized chemical to your maintenance plan, refractory organic compounds dissolve in less than 24 hours of uninterrupted filtration. If you want to eliminate cloudiness at its source without carrying out major water changes, this treatment reactivates the technical system’s biocidal capacity and immediately restores clarity to your pool.

HTH chlorine compounds must always be kept in their original, tightly sealed container in a ventilated, dry area protected from direct sunlight. As a powerful oxidizing agent, it requires strict handling precautions during storage:

• Keep a minimum safe distance of 2 meters from pH reducers or liquid acids.
• Avoid contact between the granules and organic matter, oils, or solvents.
• Handle the product with dry gloves and protective goggles to avoid irritation to the skin or mucous membranes.

Following these technical guidelines, the product retains its oxidizing stability intact for several seasons without diminishing its disinfecting capacity on piscinasyproductos.com.
