Pool Tips

One of the most asked questions by prospective pool owners is: "Which is better, fibreglass or gunite (concrete)?" If the customer asks this question in front of enough pool 'professionals', they'll get a barrage of answers, all different, for a number of reasons.

If you ask a pool salesman who sells fibreglass shells: which type of pool is better, he'll swear that the best thing you can do is invest in a fibreglass shell pool. If you ask a pool builder who builds gunite pools: which is the best swimming pool to buy, he'll tell you a load of horror stories about how fibreglass pools have crumbled, cracked and popped out of the ground. He'll tell you how once you've installed the pool and the fibreglass gelcote starts to blister, you will never get the pool company back to sort out the product failure.

If you had to ask an expert in the field of the built environment, architects or engineers, I'm sure they'll say build a gunite pool, for sure! These experts would insist on making sure that the specifications are in line with those of the NSPI's (National Spa and Pool Institute). Use the correct size steel at the correct centres...etc. The key word being, NSPI. This is not to say that NSPI registered builders never make mistakes or have problems with their swimming pools, but they certainly have a vested interest in making sure that their reputation remains in tact.

If there was to be a correct answer to the question: "Which is better, a Fibreglass pool or a gunite (concrete) pool?" The winning answer would be, a swimming pool built by a registered member of the National Spa and Pool Institute of South Africa. If their name is not on the site, then they are not members.

Pool Water Testing

There are certain guidelines we should follow when maintaining our swimming pool. For the health of bathers, we should be testing our pool water at least once a week. Especially during the busy, hot and rainy summer periods. In South Africa’s Durban KwaZulu Natal, anyway.

Keep the chlorine residual between 1 & 3 parts per million (ppm). This keeps the water sanitised. Keep the pH between 7.2 & 7.6. This is the optimum pH for bather comfort and sanitizer efficiency. These are the basic tests every pool owner should do each week.

It could be that your test results are ideal (chlorine and pH) but your pool water is green or murky. This means there are other factors such as poor filtration, circulation or water balance causing the problem. The first step is to take a sample of water to a specialist pool shop that can test for chloramines, Total Alkalinity, Stabilizer, and TDS. If the pool shop is an NSPI member, then you should be in good hands. Once the water balance is corrected, if the problem persists, you may need to get a technician to call on your pool and assess what other problems may exist.

Back-Up® Algaecide is a unique form of liquid concentrate available in 500ml bottles. Pool chemicals work better when the water is properly balanced, and even though Back-Up® works in high or low pH conditions, your water will still need to be balanced in order for chlorine to work effectively.

When using Back-Up®, an initial dose of 90ml per 10, 000L of pool water is required, and then a maintenance dose of 15ml per 10, 000L per week is all you need to keep the algae at bay.

Weather conditions in South Africa, and particularly in Durban, Kwa-Zulu Natal, keep pool owners on their toes. Looking after the pool's water balance and taking precautions during the weekly maintenance routine, will save a lot of time and money.
Some benefits of Back-Up®:
• Won’t evaporate
• Won’t stain surfaces
• It’s a broad spectrum algaecide
• Can also kill Pink Algae (ask your BioGuard Dealer for instructions)

Have fun in your swimming pool this summer. Keep your pool water balanced.

Does your Kreepy work for 10 minutes after a backwash and then get sluggish until it stops? The swimming pool filter is the most underrated yet important piece of equipment your pool has. The filter is the kidney of the swimming pool and if it fails, the pool will surely not survive.

Clogged filter sand causes the swimming pool water to become cloudy and green. It also causes the Kreepy to eventually stop working. Once this happens you know you have circulation problems, on top of filtration problems.

It is quite a big task to open a sand filter and although this is often the best way to find out the condition of the sand, if you do not wear protective clothing, you run the risk of becoming very ill, especially if your sand is infected with bacteria.

The best treatment you can give the sand filter without actually changing the sand, is to recondition the sand with a filter sand cleaner.

There are many sand cleaners on the market. Be careful not to confuse a filter sand cleaner with a filter 'enhancer'. A filter enhancer usually causes the clogging of the filter by using gels or polymers in order to trap finer particles of dirt. Not what you want if your filter is already clogged!

This filter sand cleaner strips all the oil, sun lotion and any other debris that gets trapped in the sand filter. It helps get rid of the stubborn debris that doesn't come out easily with a backwash.
