Maintaining Your Spa or Hot Tub:
Proper Sanitation: Sanitizer kill bacteria and keep water clean. One of the following can be used to properly sanitize your spa water.
Chlorine- You should maintain a chlorine test kit reading of 3.0 to 5.0 ppm of available (working or free) chlorine.
Bromine- Maintain a 3. 0 to 5.0 ppm reading of total bromine.
Nature2- Mineral based sanitizer requires at least 6 hours of filtration time and the addition of an oxidizer at every use. Last four months.
Ozonator- Not acceptable as the primary sanitizer, used as an oxidizer supplementing other sanitizer.
Superchlorination: As the spa or hot tub is used, non-filterable wastes such as perspiration, oils, hair sprays, etc. can accumulate. This makes the water dull, irritating and unattractive, as well as interfering with sanitizer activity. Also known as shocking or oxidizing. In a spa the usual method of oxidizing is to add a non-chlorine shock treatment. Potassium-monopersulfate is typical of this product.
pH Control: Maintaining proper pH is extremely important for proper control of bacteria, user comfort and preventing equipment deterioration. pH is the measure of acidity and alkalinity in the water. The proper level is 7.4 to 7.6. This is a comfortable level for the soaker’s skin. If pH is high (above 7.6) chlorine sanitizers are less effective, surfaces and equipment can scale, water may cloud and shorter filter runs may occur. Low pH (below 7.4) causes sanitizers to dissipate more rapidly, increases corrosion of surfaces and equipment, and may make water irritating to spa users. pH adjustment is accomplished with: pH (up)(plus)(increaser)(raiser) or pH (down)(minus)(decreaser)(lower).
Mineral Content: Proper mineral content is also an important factor in spa water. Total Alkalinity (TA) and Calcium Hardness (CH) are the primary minerals of concern. TA should always be in the 125-150 ppm range. Low TA can cause the pH to bounce from one level to another, potentially causing scaling or corrosion of surfaces. Excessive TA levels can cause scale, cloudy water and other pH problems. Low levels of calcium (water too soft) can lead to corrosion of equipment and staining of surfaces. High levels of calcium can cause scaling of equipment (reducing efficiency) and ugly, rough patches on the interior of the spa. Alkalinity and Calcium Hardness can be raised using ‘increaser” ; to lower levels use dilution with fill water of lower content.
Stain and Scale Control: Surface staining and scaling is common in hot “pools”. Hot water tends to deposit scale more rapidly than cooler water. Rapid water circulation can cause erosion of metal components in the recirculating system and leave metallic stains on interior spa surfaces. A stain and scale control agent can be added to spa water to control.
Foaming: High aeration and agitation combined with body oils, lotions and high temperatures are likely to cause excessive foaming. Defoamer can be added to eliminate foam, but they only works on a per use basis.
Cloudy Water: Bathers may add particulate matter too small to be removed by the filter. Also, due to the initial bleeding of tannin from wood surfaces of hot tubs or heavy usage of the spa or hot tub, cloudy water may be a problem. Clarifiers are effective at assisting your filter system to remove fine particulate.
Filter Cleaning: High temperatures accelerate the release of body oils and grease into the water. These usually are deposited in the filter, reducing its ability to clear the water. Filters should be soaked in Filter Cleaner monthly to maintain their efficiency.
Surface Cleaning: Oil and greases collect quickly around the water line. Surface Cleaner can be used to remove accumulated material on spa surfaces.
Maintaining Your Pool:
Proper Filtration: Pool water must be circulated and filtered. If your filter doesn’t operate properly, neither will the products you add to keep it clean and clear. Make sure the filtration/circulation system is in clean operating order and runs long enough each day.
Proper Maintenance: The three basic steps in routine maintenance are: 1. Sanitize to kill bacteria continuously; 2. Remove wastes to make the water sparkling clear; 3. Prevent algae growth.
1. Sanitize with chlorine in the form of liquid, granular, tablets or sticks. Granular, tablets and sticks are all stabilized; meaning they contain additives to prevent the rapid deterioration in bright sunlight.
2. Remove wastes (shock) the pool about every two weeks or after heavy bather use or a significant rain. Chloromines are shocked (oxidized) out of pool water by using Pool Shock (Calcium Hypochlorite)(Lithium Hypochlorite)(Dichloro).
3. Prevent algae by supplemental additions of an algicide weekly. If algae establishes itself; determine the type and treat accordingly. Algicides are rated by strength.
