Reason for Testing: To allow Chlorine to work to its full potential and to prevent any corrosion or scale forming it is important to maintain a pH within the ideal range. The correct pH level also provides comfortable bathing conditions for the bather as it reduces the chances of irritation occurring. For example, just halving your chlorine level requires that you empty half of the pool water. Even for a smaller pool, that’s a lot of treated water to move before even thinking about the environmental impact or local regulations.

Algaecide is a chemical that both kills algal matter and prevents it from growing in the first place. It’s best utilised alongside a chlorine sanitiser as an effective tandem for keeping your pool clean. Using algaecide in your pool is recommended as part of your start-up process each season but also whenever your pool shows signs of developing or established algae. If there is insufficient calcium in the water of a tiled pool, the water will, over time, dissolve the calcium in the grout, making it soft. Eventually, the grout will disappear, leaving sharp edges which pose a cut risk to bathers. In a tiled pool, the calcium hardness should be kept above 200ppm. Calcium hardness can be increased by adding calcium chloride (calcium builder).

Length Conversion Calculator

Fi-Clor offers a comprehensive range of high quality pool chemicals and pool chlorine, ideal for your swimming pool, spa pool or above ground pool. Start by calculating the volume of water in your pool using our Pool Water Volume Calculator. Just enter the dimensions of your pool (in metres) and the calculator will work out the approximate volume of your pool (a metric converter is provided to aid you with this). Apply each smaller dose, allowing time to thoroughly circulate (2-3 hours for commercial pools/6-8 hours for domestic pools) before re-testing chlorine/bromine level and if necessary adding further doses If the alkalinity level is too low, then the water can become corrosive and uncomfortable to bathe in. The corrosion can also damage the heaters and pipe work, resulting in them ultimately failing. Pool alkalinity can be increased using sodium bicarbonate (alkalinity builder).

Maintaining the correct pH level in your pool plays an important role in how effective the chlorine is. The pH scale runs from 0-14, with 7 being neutral. Anything above 7 is considered alkaline and anything less than 7 is considered acidic.Reason for Testing: Calcium hardness is usually a problem for tiled pools in soft water areas. This is due to there not being enough calcium in the water so it will dissolve the calcium in the grout making it soft. In general this is not a problem in hard water areas as the water contains sufficient calcium. Algae are a major problem for outdoor pools. A product of low chlorine levels, poor water balance or bad filtration (or a combination of any of the three), algae, particularly if left to develop and bloom, present a number of issues for pool owners. These include potential damage to the pool, making the water unsafe for use and changing the water colour to an unpleasant aesthetic. Split this total amount into 4 smaller doses. Apply each 1/4 dose, allowing time to thoroughly circulate (2-3 hours for commercial pools / 6-8 hours for domestic pools) before re-testing chlorine/bromine level and if necessary adding further doses. This is exactly what it sounds like; a chemical that reacts with chlorine, breaking it down and effectively rendering it useless. What’s more, commonly used neutralizers work in as little as a few hours.

Just be sure to remove all chlorine sources from your pool. Turn off the chlorinator or saltwater chlorine generator, and take any chlorine tablets out of the pool skimmer or floater. You’ll also want to leave your pool cover off during this time, at least during the day. Stabilised Chlorine Tabletsare provided in two tablet sizes: 20 gramsand 200 grams. Twenty-gram tablets are designed for maintaining above-ground swimming pools (which are typically smaller) while 200-gram tablets are designed for larger in-ground pools with a larger volume of water. They are added to the water via a floating dispenser or the skimmer basket. Despite having a number of methods at your disposal, the best thing you can do to fix a high chlorine level is to just let nature run its course. Each topic will give you a complete breakdown of what the chemicals do and how to use them correctly, so you can get to grips with how to maintain your home swimming pool efficiently.Pre-dissolve the product in a clean plastic cpontainer at a maximum rate of 100g of product per 2.2 gallons (10ltrs) of clean warm water. Stir well to ensure product is fully dissolved. Carefully add the resulting solution to the pool whilst the pump(s) are turned "on", preferably near to the water inlets to aid distribution. Never mix with any other chemicals including cleaning products and chlorine products, as a dangerous reaction will occur.

Our most popular algae treatment, polyquat algaecide,is absorbed by organic debris such as leaves and dead algae, so it‘s important to clean the pool thoroughly with a brush or vacuum cleaner before starting the chemical treatment.For your pool to be safe for use, you need to maintain a suitable water balance whenever it’s in use. Water balance is defined as a condition where the water is neither corrosive nor scale-forming. The major factors in determining water balance are the pH of your swimming pool, the total pool alkalinity and calcium hardness. The nature of your local water supply plays a significant role in water balance; this is discussed in our ownership guide to hard and soft water areas. pH – what is pH balance in a pool? Chlorine gets used up as it fights off contaminants in the water, which is why it constantly needs topping up under normal circumstances. Your cyanuric acid level (CYA) plays an important role here. The more of it you have in your water, the higher this limit will be. This is because CYA effectively weakens your chlorine after bonding with it.
