- Chlorine Chemistry - Part II
In its elemental state chlorine exists as a gas. Gas is available for swimming pool sanitation. It is very cheap, and is the purest form of chlorine with no binders or carriers. The percentage of available chlorine is 100%. It is also extremely dangerous and restricted in its use. It is rare to find a pool using gas as it's sanitizer, and those that do are usually very old, very large public pools that have (we hope) enacted strict safety procedures. Gas is very acidic, with a pH close to muriatic acid, so these pools using it add a lot of base to counteract this.

- Chlorine GeneratorsOne of the first alternative sanitizers introduced to the pool and spa industry was the chlorine generator. Chlorine generators are attractive to pool owners simply because they eliminate the need to store, buy, transport and handle chlorine. They are not an alternative to chlorine, but actually make chlorine by producing chlorine from regular table salt. The pool water passes through a generator cell that introduces chlorine into the pool water.

What is most important when adding salt is to brush it around until it is dissolved. This is accelerated by turning your pump on, opening the bottom drain and adding the salt over the drain, rather than walking around the perimeter while adding the salt. It is recommended that you continue to run the pump for 24 hours so the salt can spread evenly throughout the pool. With Granular salt, 60 - 70% will have dissolved before hitting bottom. The remaining salt can simply be brushed into the drain which will then complete dissolution. With all other forms of salt, it will take longer to dissolve but the same process will accelerate the dissolve rate. Simply brush the salt in a pyramid over the drain to increase dissolution.Saturday, December 20, 2008 4:20 PM
- Chlorine Odor/ Irritation
It is a common misconception that red eyes and a strong chlorine smell to the water is the result of too much chlorine. Actually, the cause is not enough chlorine! The combined chlorine compound, called a chloramine, is produced when a free chlorine molecule combines with a nitrogen or ammonia molecule. These compounds smell bad, irritate the eyes and skin, and get in the way of free chlorine trying to do its job.Saturday, December 20, 2008 4:20 PM
- Cleaning Equipment
Along with the joy, excitement and long lost relatives that come with pool ownership there are also the maintenance challenges. There are many tools and items available to make your pool owning experience less troublesome. Even if you have an automatic cleaner, you will need the basic equipment. Telescopic pole, skim nets, pool brushes and a test kit are a must for any pool owner. The following is a glossary with descriptions of swimming pool and spa cleaning equipment.

- Cloudy, Dull, Hazy Water
Suspended micro particulate matter, interfering with the passage of light is known as turbidity. It can range from an almost imperceptible haziness to a pure, milky white color. Besides being unattractive, cloudy water can prevent the rescue of swimmers in trouble and may provide no depth perception for those who would dive into the water. This particulate matter also interferes with the ability of the filter and chemicals to properly sanitize the water.Saturday, December 20, 2008 4:00 PM
- Concrete Swimming Pool Repair As your gunite or concrete pool begins to age, the plaster will require the occasional repair. Cracking, hollow spots, sometimes called “pop-ups”, and chipping are not uncommon. As are wear spots in your pool plaster, when the plaster is worn away, and the gunite below the plaster is showing. Most of these pool plaster repairs can be done by you. With the right tools, the right materials, and a little know how, you can repair most small cracks and chips without too much effort. The following is a step by step guide to making typical pool plaster repairs.

- Controls and AutomationOne of the most common and simplest ways to automate your pool. Swimming pool filter timers are easy to install, save $$$ on electricity, and can be set to turn the filter or cleaner pump on and off when ever you want. You can set your filter pump to run from 8:00 a.m. to 8:00 p.m. and the Polaris pump to run from 10:00 a.m. till 12:00 p.m. Or select the pool operating times you want. Very easy to operate and not expensive.

- Coping Repair
First question to be asked is "have you caulked your expansion joint?" Freezing water in the joint will put pressure on the coping, breaking the mortar that attaches it to the beam. Second question will be "Is the expansion joint true, or does the pool deck touch the coping?" This pushes on the coping (and the beam) every time the deck or the pool expands.Saturday, December 20, 2008 4:22 PM

Just about all pools have some type of pool ladder or pool steps. Almost all swimming pool ladders are removable. On an in-ground installation, there is usually a bolt or some type of anchor that can be tightened or loosened to install or remove a swimming pool ladder. Above ground pools have usually just an A-frame ladder that can be folded and stored. It is important that the ladders do not damage the pool walls or floor. Rubber pads and bumpers must be inspected every year and replaced when necessary. If a step or ladder tread is broken or cracked, replace it immediately. For the safety of your guests and family always make sure ladders are in good condition.Saturday, December 20, 2008 4:25 PM
