Fi-Cor Spa Shock contains approx 15% more available chlorine than standard calcium hypochlorite. It dissolves very quickly to form free chlorine to kill bacteria and break down organic contaminant in the water that cause eye sting and bather discomfort. When filling your spa for the first time (commissioning) or when refilling after it has been empty for a period, it is strongly recommended that a shock chlorination should be carried out on the cold fresh water. Fi-Clor Spa Shock are ideal products for this purpose as they are unstabilised chlorine donors and will deliver the maximum effectiveness. The free available chlorine level should be taken to either 25mg/l (ppm) for a minimum of two hours, or 50mg/l (ppm) for a minimum of one hour.While the spa is being chlorinated to these high levels, the water must be allowed to flow to all parts of the system, regularly monitoring the chlorine residual to ensure that it does not fall below the specified level at any time. Where an air blower is fitted, it should not be run for the first 15 minutes to minimise the formation of aerosols (fine spa water mist). During shock chlorination, the pH should be maintained within the range of 7.2 – 7.6 in order to ensure maximum effectiveness of the disinfection process. It’s important that after the one or two hour shock chlorination period, the spa should be drained, thoroughly flushed and refilled with fresh water, and run at normal disinfection levels. If this is not possible for practical reasons, the spa may be left with the cover off and the chlorine level allowed to fall naturally. The spa should then be drained, thoroughly flushed and refilled with fresh water as above.Use the day before a spa party for sparking clear water.This shock pot contains the right amount of product to treat the average domestic swimming pool of 11,000 gallons

Fi-clor Spa Non-chlorine Shock 1kg Spa Chemicals Spa Chemicals As the chlorine & bromine do its job killing the bacteria it can form other compounds called combined chlorine (chloramines) or unwanted by-products from the bromination process. These compounds have no killing power and are, in fact, a nuisance. They need to be removed by periodically shock dosing the pool with Fi-Clor Spa Non-Chlorine Shock. RRP £1.00 Review this product |

Fi-clor Spa Anti Scale 1ltr Spa Chemicals Spa Chemicals The make up of the mains water supply can vary considerably across the country; you may even have a non-mains source such as spring or well water. As a result, different levels of pH, total alkalinity, calcium hardness and mineral content will be found in the water that you fill your spa with. In hard water areas of the UK or if there is a high mineral content, it is strongly recommended that Fi-Clor Spa Anti-Scale is added when your spa is initially filled with fresh water and also every time it is topped up or refilled after periodic draining. This should help to minimise scale formation and staining of the spa surfaces. RRP £1.00 Review this product |

Fi-clor Spa Dry Acid (ph +) 1.5kg Spa Chemicals Spa Chemicals The pH of your spa water is much more important for chlorine than it is for bromine. The pH needs to be kept between 7.2 – 7.6 to ensure optimum conditions for the chlorine to kill unwanted pollution. When necessary you can raise the pH using Fi-Clor Spa pH Increaser (Soda Ash) and lower it using Fi-Clor Spa pH & Alkalinity Reducer (Dry Acid). There are several reasons for operating within this band, the most important being the pH of your mucous membranes (eyes, nose, throat) is about 7.4, so the closer you can keep the pH to this, the more comfortable it will be. A high pH will lead to cloudy water and excessive scaling. Should any scaling occur, it can be removed using Fi-Clor Spa Anti-scale. Meanwhile, a low pH will create acidic conditions which may corrode the metal parts of the system. If the pH rises above 7.6, reduce it by adding Fi-Clor Spa pH & Alkalinity Reducer (Dry Acid) at a rate of 10gms per m3 (220 gall) - Calculate how much Fi-Clor Spa pH Increaser (Soda Ash) is needed for your size spa- Add this to a clean plastic jug filled with warm water (the warm water will assist dissolution). - Add the chemical to water, not the water to the chemical. - Mix the product until it has completely dissolved. - Carefully pour the solution round the spa. - Allow at least 15 minutes before retesting the pH.

Fi-clor Spa Hardness Increaser 1kg Spa Chemicals Spa Chemicals The level of calcium found in the water used to fill your spa depends on the area where you live. You will probably know the likely calcium hardness of the local mains water. Some test kits will enable you to determine the calcium hardness levels of the mains water or in the spa by reference to the total hardness bar on the strip. The ideal level depends on the type of spa shell you have: In acrylic spas calcium hardness should be a minimum of 175mg/l. In tiled spas the minimum level should be 250mg/l This should provide sufficient calcium to satisfy the water’s ‘calcium demand’. Calcium hardness can be increased using Fi-Clor Spa Hardness Increaser. In hard water areas with a high calcium hardness level, Fi-Clor Spa Anti Scale should be added as per the instructions on the label to prevent scale formation. RRP £1.00 Review this product |
