POOL EQUIPMENT SALES
Our services include vacuuming the pool floor, netting the top, brushing surfaces like walls and steps, filter maintenance, balancing chemicals, adjusting chlorinator output, calibrating pH and chlorine sensors and adjusting set-points, changing filtration times, checking water levels and inspecting equipment for correct operation, equipment sales and installation, resolving in-floor cleaning problems, blockages, leaks or other water-flow issues.
If you’re in the McKinnon area, investing in our expert routine pool cleaning and maintenance means your pool is always getting the best care. With the stress removed about safety, functionality and potential deterioration of your pool, you can lay back and enjoy your pool on every swim day or night.
At first visit, we chemically dose your swimming pool to kill the algae. As the alage dies it turns white and will float to the top. Once the alage becomes water-logged it will drop and settle at the bottom of the pool. All during this process the dead algae is suspended at different levels in the water and your pool will look quite cloudy.
On average it takes 3-4 days for all of the dead algae to settle on the bottom and for the pool water to become crystal clear. We will then return and vacuum your pool to waste, so it’s ready for use.
This circulation also assists any chemicals added to be evenly distributed throughout the pool water. The ongoing combination of water circulation, the filter removing contaminants and particles from your pool at McKinnon and the correct chemical balance being maintained, will have your pool water fresh, clear, clean and healthy.
Media filters require backwashing for two minutes each month. During this process particles that have been trapped by the media are flushed out of the filter the opposite direction to which they became trapped… hence the term “backwash”. Sand media is required to be replaced every 5-6 years and glass media every 10-12 years. Sand will filter and catch particles to approximately 25 micron and glass down to 3 micron.
Cartridge filters need to have the elements removed and rinsed with a hose monthly to remove any dirt and other particles collected. Cartridge element manufacturers recommend that elements are replaced every 12 months. Cartridge filters will filter to around 10 micron.
Our team at McKinnon are experts in the maintenance of both filter types and we’re available 7 days a week to be of service to you when required.
Water quality management is a combination of adequate filtration times, water circulation and maintaining the correct chemical balances.
Rain will also affect the chemical balance of your water because it has a pH of around 5 (which is quite acidic & why the term “acid rain”) and will lower both the pH and alkalinity. Other chemicals will become diluted because rainwater doesn’t contain chemical additives.
Correctly balanced water ensures a healthy pool, so we add any required chemicals at each maintenance visit (if and when needed), to ensure your pool is always safe for swimming.
The pool water Saturation Index (SI) at a value of zero is balanced. Values above zero can cause scaling on the pool wall or floor surfaces and below zero the water will become corrosive risking damage to your pool shell and equipment.
Chlorine is used to disinfect and sanitise the pool water, but pH needs to be within a range of 7.1-7.8 for chlorine to be properly effective.
If pH is too high the water becomes alkaline, which reduces the disinfecting capability of chlorine. If pH is too low it will cause the chlorine to be quickly consumed, which will require more chlorine to be frequently added.
Chlorine is added to your pool automatically though your chlorinator or liquid chlorine feeder, manually adding granular or liquid chlorine, or using chlorine tablets. High levels of chlorine are usually reduced by the UV rays from the sun. Chlorine levels can be brought down quickly by adding sodium thiosulphate to the pool water and leaving the pump to circulate for 3-4 hours to evenly distribute this chemical throughout the pool.
Hydrochloric acid is used to lower pH and soda ash added to increase pH levels.
And if you live in McKinnon, then you’ll understand that during summer the temperature and UV can become extreme.
Stabiliser acts as sunscreen for chlorine. Without stabiliser, chlorine can lose 80% of its effectiveness within two hours on a hot summer’s day. With the correct level of stabiliser, chlorine is shielded from the sun and will only lose about 10% of its effectiveness in the same time period. This means stabiliser is needed in pools to help the chlorine maintain its effectiveness when exposed to the intense Australian UV rays.
Stabiliser levels also need to be monitored carefully, because if there‘s too much it will reduce the capability of the chlorine. If there isn’t enough, then the chlorine won’t be protected from the harmful UV rays.
The only effective way to reduce stabiliser levels is through dilution. This requires your pool to be part-drained, water added refill your pool and the chemicals rebalanced.
Buffer is used to increase alkalinity and hydrochloric acid is added to lower alkalinity.
We are in the McKinnon area every day, we can digitally analyse your water while we are servicing your pool, which will give you peace of mind knowing that your water chemistry will be always correct.
