Pool Chemicals

This is the part we love – water chemistry. Water chemistry and the marvel of the salt water chlorinator, ensuring the system is all working correctly and right chemicals are in balance

Water Testing

To test your pool water, we invest in the best devices to do so. We use LaMotte3585 WaterLink® Spin Touch® DW Photometers. They take the most accurate reading available, then Bluetooth to our iPhones to sync with your pool service history to assist us provide the best treatment possible.

Spintouches test for phosphates which means we can treat and remove unsanitary phosphates from your pool so ensure you’re swimming in fresh, clean, pure water.

This provides accurate results for:

Chlorine,  pH, Alkilinity, Hardness, Cyanuric Acid, Copper, Phosphates, and Salt

Once we’ve established your pools chemical state, we can then apply the correct balance of chemicals to keep your water perfectly sanitised for the next period.

As an Aquamagic client, your pool chemical supply is guaranteed all year. Our regular clients are never without salt during the periods of extreme salt shortage.

We source and supply premium pool chemicals, from the leading suppliers, utilising safe and secure transport logistics.

Most saltwater pools require a salt level of between 3000 – 5000ppm. Far less than say, the ocean, which is around 36,000ppm.

We test your pool water using the SpinTouch and often a saltmeter and then add the necessary amount of salt to increase your pools salinity to the correct amount. The salt dissolves in the pool and is then ready to go to work.

When the pool is running and the chlorinator is on, during the timer cycle, the saltwater moves through the system. After passing through the filter, and before it is returned to the pool, it passes through the salt cell.

The cell is made up of parallel titanium plates that are coated in ruthenium or iridium – very hard, non-corrosive and expensive metals. The chlorinator controls the chlorine output by way of electrolysis to the plates and the dissolved saltwater passing through creates a chemical reaction. The reaction produces chlorine gas (hypochlorous acid and sodium hypochlorite) This gas flows back into the pool with the filtered water and goes to work to sanitising the pool killing off all the harmful bacteria, fungi and algea. When the gas is used up in the sanitising process the salt as NaCl and the process starts again when the water passes through the cell.

As you can see the salt to chlorine, chemical process doesn’t use up the salt since it’s returned to salt once the chlorine molecules have done their sanitising. The reason we add salt is to do with dilution. Due to the high levels of rain on the Sunshine Coast pools are constantly being diluted and we therefore need to keep adding salt to maintain the levels where your chlorinator needs to operate.

Too lower salt levels can damage the cell which is expensive to replace, cause scaling in the pool and on the equipment and reduce free chlorine, leading to poor pool health.

We apply ultra fine Pool Pro pool salt. This way we can ensure no salt staining, or worse metal staining caused by salts that are high in iron and metals. TIP: if you have brown staining around the return jets in your pool, contact us to discuss a stain treatment and then switching to a quality, ultra fine salt to ensure it doesn’t reoccur.

The optimal pH level for your pool is between 7.2 and 7.6. At this pH level, the water is perfect on your skin and comfortable on the eyes. This pH level also indicates that the chlorine levels of the water are high enough that the growth of fungus, bacteria, and algae is kept to a minimum. At the right pH levels, your pool won’t develop scale. When pH rises too high minerals start to leave the water, this leads to staining, calcification, murkiness and other problems. The critical balance is further highlighted with the fact that chlorine becomes less effective as pH rises above our ideal pH range.

We humans feel more comfortable around middle of the pH range (1 – 14). Ie The pH of our tears is 7.4. Keeping your pool at the same level causes far less irritation to your eyes when swimming. So whilst chlorine works best below this, the acidity will irritate our eyes and skin at those low levels. We control pH using Hydrochloric acid to lower the pH Warning: Hydrochloric acid is a corrosive substance with harmful fumes. Handle with care being careful not to breath fumes, wear protective equipment (PPE) such as boots, gloves, eyewear, mask or breathing apparatus. Always add acid to water not water to acid. Remove swimmers from the pool whilst adding acid and for a period of dilution following. Hydrochloric acid is a highly effective pool cleaner and has a number of uses around the pool. Is can clean walls and floors, remove scale and kill algea. We use various dilution ratios to perform many tasks from cleaning saltwater cells to acid washing entire pools. Hydrochloric acid is consistently used to lower the pH of the pool. Too higher pH can also cause issues with the normal pH of your body, which might lead to a condition known as metabolic alkalosis. The development of this health condition can bring about such symptoms as vomiting, nausea, confusion, hand tremors, and muscle twitching. pH is so important many pools have an automatic acid feeder. We recommend a pH Boss. It monitors your pools pH and dispenses acid to maintain a balanced pH level. We then fill its drum with a diluted acid mix when doing the regular pool service at your house.

Ideally we’d like to keep your pool’s alkalinity between 80 – 120ppm

We use Sodium bicarbonate (baking soda) to increase the Alkilinity and pH of pools.

Maintaining an alkalinity between 80 and 120ppm is ideal. Alkilinity is a measure of how much acid your pool water can absorb. It does this by absobing hydrogen which is uses to create neutral bicarbonate ions, keeping the pH stable and the pool clear.

Otherwise referred to as Stabiliser, and sometimes UV block is ideal between 50 – 80ppm

Stabiliser works to make the chlorine last longer in your pool. The pure chlorine created by the salt and the electrolysis is unstable, meaning it degrades in sunlight. The stabiliser helps the chlorine to last long enough to kill bacteria and sanitise the pool. For this reason it is one of the most important pool balancing chemicals.

We need to test the hardness of your pool water and keep it in a range between 200 – 400ppm

When pool water becomes too soft ie the hardness falls below 150ppm, it becomes corrosive and will take what it needs from any surface by destroying, grout, tiles, concrete, pebblecrete and other surfaces.

Once the damage is done there is no way of fixing it other than with expensive, resurfacing. This is why it’s imperative we regularly monitor the water and balance the pool to keep the water hardness over 150pp at all times.

We do this by adding Calcium Increaser, otherwise known as Calcium Chloride.

We service and maintain Bioniser pools. Bioniser pools use copper as a sanitising agent. Our SpinTouch accurately measures for the amount of copper, critical to the sanitisation for the Bionizer pools.

Bionizer are a fantastic pool product and method for maintaining pool health. We maintain many Bionizer Pools from Noosa to Caloundra, supplying, installing, maintaining and repairing all the Bionizer equipment

 Our ideal Bionizer pool chemistry readings are:

 pH 7.0 – 7.4

 Copper 0.5 – 0.6ppm

 Total Alkilinity 80 – 120ppm

 Hardness 200 – 250ppm

 Phosphates below 500ppb
