What is a Chlorinator? | Convenience, the experienced pool owner’s choice

How do Pool Chlorinators Work?

 

Chlorine in one form or the other has been in use in a wide variety of industrial applications for a long time, and in that time we have come to understand it extremely well. Although there are some people who believe chlorine in pools poses a safety hazard, clinical studies have found no such link – either to swimmers or the environment. This is why nearly every pool in South Africa continues to employ chlorine as a free-ranging antibacterial agent, keeping the water clean and clear and maintaining an essential level of purity for recreational use. If you own a pool, however, you know that regulating chlorine can represent something of a hassle.

The reason for this is actually quite simple: chlorine breaks down over time when exposed to sunlight. Although hypochlorous acid – the essential byproduct when you (more…)

Fibreglass vs Marbelite pools

Published by Swimming-Pool-Expert on June 24th, 2011

New Pools – The firbreglass or marbelite choice

Fibreglass lined concrete swimming pools offer all of the benefits of pre-formed, factory-moulded pools. In fibreglass lined pools, the structural strength is provided by the concrete, brick etc. structure of the pool. The surface finish of a fibreglass lined pool, whilst not as smooth as a premoulded, factory-built fibreglass pool, is smoother and less porous than gunite or marbelite plaster.

Fibreglass linings are applied to existing gunited or marbelite pools either for cosmetic reasons i.e. to offer an attractive finish which is strong, durable, and requires minimal maintanance, or for functional reasons, i.e. to provide a waterproof lining for pools that are prone to leaking. Cracked or leaking concrete pools must be repaired and correctly prepared prior to application of a fibreglass lining.

In either case, the fibreglass lining will provide a skin that is strong, durable, and requires minimal maintanance. More and more homeowners are finding that fibreglass lined pools are stronger, more durable and less susceptible to surface degradation or cracking, than pools made from more conventional materials.

Fibreglass reinforced polyester (GRP) composite materials, is the material that is revolutionising the pool industry by keeping water in whilst maintaining its good appearance and ease of maintanance.

Compared to a concrete or marbelite pool, a fibreglass lined pool is generally less costly to maintain on a daily or monthly basis. This is important to the pool owner, because a clean pool is a healthy pool. It is estimated that owners of a GRP-lined pool will enjoy enough savings in a 12-month period of having the GRP lining, to pay for the cost of the lining.

The savings come about through significant reductions in the chemicals required during summer, to maintain well balanced, crystal-clear water. Saving also accrue bacause the (more…)


How to acidwash a pool

Published by Swimming-Pool-Expert on June 24th, 2011

Acid Washing

You will have to drain and clean your pool before you start. An acid wash becomes necessary if the pool has turned into a swamp. This may occur if the pool has been stagnant for a period of time so that algae has taken over.

The general rule of thumb for determining the need for an acid wash is: if you can see the bottom of the pool (the floor) then you can bring it back with chemicals, labour and filtering. If the floor is not visible, the cost of the chemicals and labour will generally be greater than the acid wash charge, and take much longer. Also, extensive algae blooms will stain plastered pools, making an acid wash desirable and if there are any other stains maybe from metals.

An pool acid wash is, put simply, purposeful stripping of a tiny layer of liner, exposing fresh plaster beneath. Therefore, it is not advised to make it an annual custom, which will accelerate the need for re-plastering. Most plaster coats (sometimes called marble plaster or marblite) are in excess of 8mm, so a few careful acid washes should not hurt.

You may also decide on an acid wash not because of swamp conditions, but just to bring out a brighter, whiter finish. Mineral stains caused by excessive (more…)

Beautiful swimming pool

Great news for swimming pool and spa owners was announced yesterday by Hendrik Ehlers, franchisor of Swemgat in South Africa, when he said:  “We want to make swimming pool maintenance easy for pool owners by publishing a practical DIY pool care manual and comprehensive advice for free

Ehlers is convinced that a swimming pool is much better home entainment than watching TV.

 

 

 

He says the following reasons distracts home-owners from owning a pool, but that Swemgat want to change them for the better:

  • The swimming pool industry’s bad reputation;
  • Poor after-sales service;
  • Potential hassles with swimming pool maintenance and difficulty to find free advice;
  • The lack of professional pool care instructions from pool builders;
  • The view by some people that a swimming pool is a luxury; and not an investment in health and after-work family entertainment.

With free access to the Swemgat swimming pool manual, pool ownership will (more…)
