Blue Horizons Aquasparkle Spa TA Plus 1kg 1kg

Blue Horizons Aquasparkle Spa TA Plus 1kg 1kg

AquaSparkle Spa TA Plus is a measurement of the waters ability to resist pH change. If the total alkalinity is low then the pH can fluctuate making it difficult to control and maintain at the ideal level. If the total alkalinity is high then the pH can be difficult to change and will keep rising. A high total alkalinity can also lead to the formation of a bicarbonate scale on spa surfaces, within pipework and support equipment. If the total alkalinity of your spa water is below 80mg/l it should be increased using AquaSparkle Spa T.A. Plus, the table below indicates the dosage quantities required: AquaSparkle Spa TA Plus Dose Rates: To Increase TA in 1,000 Litres by 10mg/l requires 18g of TA Plus To Increase TA in 1,000 Litres by 25mg/l requires 45g of TA Plus To Increase TA in 1,000 Litres by 50mg/l requires 90g of TA Plus If the total alkalinity of your spa water is above 150mg/l then AquaSPArkle Spa pH Minus can be used to lower it. When applying Spa pH Minus to lower total alkalinity levels, the product should be predissolved and then slug dosed (dumped) into one area of the spa. The dose rates are indicated below: AquaSparkle Spa TA Plus Dose Rates: To reduce TA in 1,000 Litres by 10mg/l requires 24g of pH Minus granules. To reduce TA in 1,000 Litres by 25mg/l requires 60g of pH Minus granules. To reduce TA in 1,000 Litres by 50mg/l requires 120g of pH Minus granules.

Blue Horizons Kibbled Aluminium Sulphate 25kg 25kg

Blue Horizons Kibbled Aluminium Sulphate 25kg 25kg

Kibbled Aluminium Sulphate sinks unwanted debris to the pool floor creating clear sparkling water. Once the particles have settled on the pool floor they should be vacuumed to waste. Alternatively, dose pre-filter via a tank and pump system to improve filter efficiency. This product should only be used in pools with sand filtration. . Kibbled Aluminium Sulphate, commonly known as alum is a hard crystalline solid or powder that is soluble in water. It contains around 17% alumina (Al2O3). It is manufactured in a simple process from aluminium trihydrate and sulphuric acid. Kibbled Aluminium Sulphate Uses: - Kibbled Aluminium Sulphate is used in water purification. As a mordant in dyeing and printing textiles. In water purification, it causes impurities to coagulate which are removed as the particulate settles to the bottom of the container or more easily filtered. - Kibbled Aluminium Sulphate is sometimes used to reduce the pH of garden soil. The gardener can add Aluminum sulfate to the soil to reduce the pH level which in turn will result in the flowers of the Hydrangea turning a different color (see below). - Kibbled Aluminium Sulphate is the active ingredient of some antiperspirants. - In construction industry it is used as waterproofing agent and accelerator in concrete. - In paper making the alum reacts with rosin sizes of various types, helping to attach the newly formed rosin aluminates to fibres. Sizing makes the paper water resistant. - It is also used in styptic pencils. - It can also be very effective as a molluscide, killing spanish slugs. Kibbled Aluminium Sulphate is considered to be a relatively environmentally friendly treatment for slugs compared to the more toxic conventional products like metaldehyde.(See below - How to use Kibbled Aluminium Sulphate to kill slugs)

Blue Horizons Chlorine Stabiliser Granules 2kg 2kg

Blue Horizons Chlorine Stabiliser Granules 2kg 2kg

Blue Horizons Chlorine Stabiliser Granules is a traditional, granular chlorine donor that is still popular with many pool owners that like dose rate flexibility. These granules are rapid dissolving making prep-dissolving and application easy.

Specifically recommended for pools between 5,000 gallons (22,700 litres) and 15,000 gallons (68,175 litres). As a guide, an 18ft round pool that is 48 inches deep contains 4661 Gallons (21,182 litres). The dispenser comes fully loaded with chlorine - so there is no need to touch any chemicals in the process, simply place into your swimming pool and let the dispenser do the work! Comes loaded with: - Sanitiser (Chlorine), to keep the water disinfected from bacteria. - Clarifier, to keep the water sparkling clean and improve water clarity. - Algaecide, to prevent algae in the long term, alongside the sanitiser. - Sun Stabiliser, to protect sanitiser (chlorine) levels from the sun. Feactures - Blue Horizons Fully Loaded Floating Chlorine Dispenser 1.5kg for Swimming Pools - Recommended for pools between 5,000 gallons (22,700 litres) and 15,000 gallons (68,175 litres). - The built in chlorine slowly erodes over a period of 3-5 weeks. - See 'directions for use' for more detailed usage guidance. Diirections of Use: Prior to using this product, ensure PH level is in the ideal range of 7.2 to 7.6. You may need to shock dose before use to establish a chlorine level in the water quickly. You can use Sodium Hypochlorite (liquid chlorine) or Calcium Hypochlorite to achieve this. Ideal for pools up to 5,000 gallons (22,700 Litres). Remove the two perforated sections of the label marked with 'tear here' and also remove the two security seals. To choose your setting and therefore the rate that the dispenser will dissolve in the pool. As a guide (only) use the x small setting for pools up to 3,000 gallons and small setting for pools above 3,000 gallons. If Free Chlorine levels are outside the desired 1-3mg/l (ppm) range - either too high or too low then adjust the base to expose to more chlorine or less. This is only a guide, as a number of factors affect chlorine level including bather load, weather, rain etc. Place the dispenser in an upright position in the pool and hold for a few seconds until the cartridge fills with water then release to float on the pool surface. Do not submerge the dispenser completely or block the vent holes. The dispenser will tip over when spent. A tilting dispenser at a 45 degree angle is an indication of imminent replacement required and sanitiser output diminishing. When removing the spent dispenser, cut open the base and place remianing tablets in the weir or skimmer basket. Blue Horizons Ultimate Multifunctional Floating Dispenser General Precautions Dosing - Wear eye and face protection and ensure granules are not blown back into your face. - Never mix with other chemicals including household cleaners as a dangerous reaction may occur. - When pre-dissolving always add product to water and not vice versa. Handling/Storage - Handle products in a well ventilated area - preferably outdoors. - Wash hands after use. - Ensure chemicals do not become damp in storage - store in a cool dry place.
