Filter and Filtration
We provide up to 25 pounds of diatomaceous earth per year to those customers that have D.E. filters. Please advise our office at least 2 working days prior to your service day, if you need some. ADEQUATE FILTRATION IS AS IMPORTANT AS GOOD WATER CHEMISTRY. With the dramatic increases in energy costs, some people try to economize by reducing the filtration time of their pool. This often counteracts our efforts to keep your pool sparkling clean. We will provide the proper water treatment but you must see to it that your pool is properly filtered. It is important to note that each and every drop of your pool's water is pumped through the filter 3 times each day to assure that it has been properly and adequately filtered. To accomplish complete filtration of the water, we recommend the following for average size pools:

                               Sand Filter 10 - 12 Hours a Day     •     Cartridge Filter 9 - 10 Hours a Day     •     D.E. Filtration 8 - 10 Hours a Day

* Allow for longer filtration times for Larger pools, those with heavy activity, and if the pool gets a lot of debris or pollen. If you have a solar heating system, you will want to increase the recommended time by 50%.

Our service personnel will advise you, by means of a door hanger on your front door, if your pool requires more filtration. It is in your best interest to follow the recommended filtration times. Filters should be cleaned when the pressure indicated by the pressure gauge on the top of the filter rises 7-10 lbs. above the clean pressure.

It should be noted our standard "Chemical Only" service does not include cleaning or otherwise maintaining the pool filter. This would solely be the responsibility of the homeowner. For those who have the "Chemical Plus Brush / Basket / Filter" service and those with "Standard Full Service" and "Premium Full Service", would receive full filter maintenance. Purchase cost of replacement cartridges, parts, and equipment, would be the homeowners responsibility at a discounted cost for having the service.

The most common cause of cloudy water is inadequate filtration. Increase the filtration time and the problem should resolve itself (see Filter and Filtration). If it does not, you may have a malfunction in your filtration system. We offer filter repair, so please contact our office for prices and to schedule repair. (727) 765-POOL.

Eye Irritation
You may have heard that chlorine causes eye irritation. This is simply not true. The fact of the matter is the eye irritation is caused by:
•Inadequate filtration (most frequent cause)
•Ammonia introduced into the pool water by means of urine. (One small child urinating in your pool can cause very heavy eye irritation for up to 24 hours).
•Organic material introduced into your pool by adding fresh water before swimming. (Always add water AFTER you swim - NEVER BEFORE)
•Leaving a pool blanket on your pool during the day. Water needs to be exposed to air. Please remove the blanket during daytime hours.
•Perspiration in the pool. Always shower before swimming.

Stains are unsightly, especially when they decide to show up in your pool. There are many different types of stains. Therefore, we will try to touch on the ones that are most commonly seen.

Dirt Stains
Looks like a brown stain. If caught early, it can be brushed away. If not, a special treatment can be done to help remove it. It is caused by dirt in the pool and suntan oils that bathers use.

Copper and Iron Stains
These are metals that are naturally present in any water supply. Some are so small your filter can't filter them out. The copper gives off a blue to gray color where the iron looks reddish-orange when they accumulate in the pool over a period of time. At some unpredictable point, these dissolved solid molecules of metal will separate themselves from the air and water molecules. From being in the presence of chlorinated water, these molecules will oxidize (rust) and present themselves as a stain in the pool.

Fertilizer Stains
Looks like spots of rust in your pool. It cannot be brushed off. The only way to rid yourself of this type of stain is to use a mild abrasive sandpaper or to acid wash the pool.
(Be extremely careful when applying chemicals to your lawn)

Chlorine and Staining

There are many sources that contribute to the accumulation of metals or minerals in swimming pool water. These often cause "staining" of the pool surface. It is not possible to guarantee that staining will not occur in a pool or that the simple addition of chlorine will not cause the settling of metals from the water once it becomes saturated with metals. Scale, stains, discoloration and cloudiness in a pool are caused by the settling out of (precipitation) metals in the water. If the precipitated metals form a hard deposited on the pool walls, they are called stains. Superchlorination is essential to proper swimming pool maintenance. When superchlorination is done with any form of chlorine, i.e., sodium hypochlorite, calcium hypochlorite, sodium dischloroisocyanurate, and trichloroisocyanuric acid, there subsequent staining of the pool. Chlorine or acid in and of themselves cannot cause stains. Chlorine bleaches and acid are used to remove stains from pool finishes. Therefore, even though staining may seem to be caused by the chemicals themselves, this is not possible. In other words, iron stains can only be caused if iron exists in the water. Copper stains, only when copper is in the water, and so on. Lack of filtration may cause stains to appear sooner, The pool water needs to be circulated the recommended time for the type of filter. Otherwise, the precipitation of the metals on the plaster is accelerated. If you do find staining to be a problem with your pool, contact our service department.

Colored Plaster Pools
The swimming pool industry is fully aware that all colored plaster pools become mottled and blotched sooner or later. Quite often a light colored ring will appear around the main drain or the plaster will appear uneven in color. This condition is typical of all colored plaster and is simply the nature of colored plaster pools. there is nothing that can be done from a service point of view to prevent or cure the blotching, streaking or mottling that will occur. Blotching may be gradual or appear seemingly overnight even after the pool is several years old. All pool builders or plaster companies require their customers to acknowledge that blotching is a normal occurrence in colored plaster pools.
