Tips for looking after your swimming pool

Bahamas Pool

Here are some simple tips to keep your pool in great condition

Tip # 1

Water Balance is the key to ensuring everything works well, by regular monitoring you will be able to control any fluctuations and get on top of problems quickly. During warmer weather when pools are used more frequently it should be tested at last every two weeks as a minimum.

Tip # 2

Check your equipment regularly, your pool equipment is subjected to:

• harsh chemicals
• The environment
• Everyday operation
• Chemical imbalances
• Bather overload ( That's lots of people )
• Animals ( Yes all types of animals love hiding in your equipment where possible )

If you notice any leaks or your cell has calcium carbonate encrusted on the plates or your pump is making a strange noise or anything that just doesn't look right, then ask your local pool shop about it and get it fixed. Leaving any problem can result in big costs to fix if not done early.

Tip # 3

Clean your filter.

Any filter such as a sand filter or cartridge filter must be cleaned often.

Filters are the lungs for your pool, dirty filters means dirty or cloudy pool.

Sand filters must be back-washed and rinsed when required, most have pressure gauges and once the pressure hits an upper limit you must do this, by not back-washing and rinsing ( it is important to rinse, just imagine this process like a dishwasher, first you clean ( back-wash ) the you must rinse to get rid of all the dirt, if this is not done together, then you are only putting the grime back into the pool )

Cartridge filters need to be taken out and hosed down frequently, at least every two weeks, if the filter still looks dirty after hosing down then you may have to soak this in a cartridge cleaner solution and this will break down all of the fats or dirt which will be cleaned more easily.

If your pool water looks cloudy all the time even after cleaning filters then it may be time to change your sand filters media or a new cartridge is required. Typically you will have to change these every 7 to 10 years depending on bather load or usage of the pool or spa.

Tip # 4

Clean your pool often.

You need to spend as much time vacuuming your pool as you do cleaning your home, even more if there is a lot of debris falling into it. Dirt, dust, plant material or animals can quickly turn a pool into a swamp which isn't pleasant, phosphates will infiltrate your pool water and with this plus debris provides a paradise for algae to grow.

The costs of cleaning up algae and balancing your water again, far out weighs the cost of vacuuming your pool, this is why pool cleaners and robot pool cleaners are so popular as these do all the work for you, it's not a sin to use one as we are all time poor and well worth the money.

  

Tip # 5
Your pool is a luxury destination.
Look after your pool and it will look after you with years of enjoyment, it is a fun place for the family an entertainment hub for bbq's, pool parties or just a place to escape from the world to be by yourself, your own private oasis.

Calcium in pool water

Calcium the Good and Bad

Calcium hardness is the measure of dissolved calcium found in your pool. If these levels are not right, then it can lead to damage to your pool and equipment.
Calcium levels are sometimes overlooked when testing but it is an essential element of water balance and should not be overlooked so should be tested regularly as well.

Calcium hardness in your pool or spa is measured as calcium carbonate which is not very soluble and can easily drop out of solution especially when water temperatures increase or poor water balance.
This can be noticeable by having calcium deposits form on surfaces of equipment or your pool and spa.

The ideal levels are between 80ppm and 400ppm, 200 being ideal, i also recommend that the warmer your water temperature, the lower the level you should have to help eliminate the calcium carbonate from forming on surfaces.

Low calcium hardness levels can result in corrosive water.
The surfaces can be affected, tile grouting can soften and eroding of equipment even leading to rusting will eventuate with the aggressive unbalanced water.
Staining can also be a problem with low calcium, though using course salt with iron or metals present is the main instigator of pool staining.

To correct low calcium levels, just add the required amount for your volume of pool or spa water and increase this but stay at the ideal range for optimum water balancing.

High calcium hardness levels can result in scale formation on pool surfaces and equipment. As the below picture can demonstrate. This a picture of a pool cell from a chlorinator and cell combination which converts salt or minerals in your pool to chlorine.

As you can see the cell has been covered in calcium carbonate, once this happens the cell will not be able to operate correctly, thus your chlorine levels will be low or non existant leading to other problems.
To correct this you must clean off the calcium carbonate.

The best way to clean it is with either a dedicated cell cleaner solution from your pool shop or you can use Hydrochloric Acid and Water in a bucket. Dilute One part Acid to 10 Parts Water. Soak the cell in it, but do not submerse any wiring only the plates.
The calcium carbonate will fizz and come off the cell, the time duration will be dependent on the severity of calcium carbonate deposited on your cell. Leave until clean then rinse off and replace back into it's housing.

Other associated problems with high calcium hardness levels will be:

• Cloudiness of pool water
• Scale forming on equipment
• Clogging of pool filters
• Clogging of heater elements
• Possible eye and skin irritations
• Scale forming on pool and spa surfaces

Along with correct water balance, adding water softeners may aid in a reduction of scale formation or carefully pouring Hydrochloric Acid on any surface formation can remove it as well.

Other tips are when building a new concrete or tiled pool it is essential to monitor your calcium levels weekly as this is quickly absorbed  by the concrete itself. If a good balance is not keep at these early stages it may lead to leaching of calcium from the lime in the cement onto the pool surface, tiles and pebble will fall off and calcium nodes will form on surfaces as well.

If your calcium levels are constantly falling this may also be an indication of a leak in your pool. 

Next we will discuss a few of the other elements essential to pool water quality.
