Spa Problem Solving

Hot Tub Problem Solving

This section will quickly help you identify and correct problems. If you have any concerns about your hot tub not dealt with here, take a water sample to Pools by Angelo.

Algae | Cloudy Water | Colored Water | Eye and Skin Irritation | Foaming
Odor | Scaling | Surface Discoloration | No Chlorine Reading | Sanitizer

1. Algae

Algae is an unusual problem in hot tubs. Algae takes on the form of small flakes that appear to be like tissue paper. Algae may consume large amounts of sanitizing chemicals. Algae in a hot tub is due to insufficient sanitizer addition. If algae is present in your spa please consult Pools by Angelo for the Purity White Algae Elimination Treatment. A daily sanitizer residual will prevent the growth of algae.  ^ Top

2. Cloudy Water

Water may become cloudy for several reasons. The most common are:

(A) High dissolved solids (combination of chemicals, bacteria, skin particles, sweat, skin moisturizers, shampoo, etc.). Solids accumulate in your tub water due to heavy bather use or chemical overload over a period of time. These dissolve and become part of the general water chemistry. When these dissolved solids become too concentrated, water clarity deteriorates. The best solution at this point is to drain the tub, clean it and refill with clean, fresh water.

(B) High PH. High PH in excess of 7.6 can cause water to cloud. Reduce PH to the proper level of 7.4 to 7.6 with Spa Minus. Attention all Lithchlor users: Each time you shock with Lithchlor it raises PH (so keep your eye on the PH reading).

(C) Poor Filtration. Check your filter for proper operation and rinse in a sink with water once per week. If the filter is dirty, the flow of water is restricted and efficiency reduced. The filter should soak in a filter cleaner (in a pail) overnight once per month. Also, program your filtration cycle to run for 4 to 6 hours per every 12 hour period. If you are expecting company (ie. Having a Party) be sure to reprogram your cycle to be on FC or full cycle for a day or so after your get-together.

(D) Chemicals were added too quickly. Chemicals were added to the water without allowing adequate time to let them dissolve before you added the next chemical. Be patient. Use your spa start-up sheet that we provide and also your daily and weekly procedure sheet for durations between adding chemicals.  ^ Top

3. Colored water:

Copper from equipment fittings and pipes dissolves into the water due to high velocity and or low PH, low alkalinity and low calcium hardness. This can show up as a greenish-blue residue in the water. Your water may also contain other minerals such as iron, manganese and copper. To prevent these stains use ELIMINATE 1 initially and ELIMINATE 2 weekly.  ^ Top

4. Eye and Skin Irritation

(A) High PH..... PH that is too high may irritate skin and eyes. Correct by adding SPA MINUS and bring PH down to 7.5

(B) Low PH...... PH that is too low may also be irritating to your skin and eyes. Have total alkalinity checked first by Pools by Angelo. If Total Alkalinity is in range (80 -120 ppm) then raise PH by adding SPA PLUS to increase PH to 7.5

(C) Chlorine. Chlorine combines with nitrogen from body wastes, oils, etc. to form chloramines. These cause the familiar chlorine odour and irritations. When the water smells of chemical, odds are that your spa actually needs to be super-chlorinated, thus killing any bacteria that may be producing in your water. Use LITHCHLOR per label recommendations  ^ Top

5. Foaming

Foaming is a common ailment in spas, caused by agitated water, dissolved solids or low calcium hardness levels. High or low PH may also come into play here. Make sure that your water is balanced and that your total dissolved solids are in a desirable range by having it tested at Pools by Angelo. If everything looks OK, use FOAM FREE sparingly. About ten drops is enough to disperse foam in an average spa. If problem persists have the calcium hardness level checked by Pools by Angelo. In extreme cases you may have to replace the water, clean the tub and refill using clean water.  ^ Top

6. Odor

Odor is generally a PH or chlorine or bromine problem. Check the PH, free chlorine and total chlorine level in the water. It may also be caused by high concentrations of total dissolved solids. To correct, shock with LITHCHLOR as per label and adjust PH to 7.5. If this does not correct, drain water and refill spa.  ^ Top

7. Scaling

Scaling is common. These rough, hard deposits can clog or coat circulation lines, heater pipes, heater elements and filter lines. This restricts water flow and may cause severe, expensive damage to parts and equipment. Scale is usually the result of undissolved calcium which precipitates and becomes calcium carbonate when PH is too high. To prevent, maintain your 7.5 PH and total alkalinity at 80-120 ppm. Add ELIMINATE 2 weekly.  ^ Top

8. Surface Stain and Discoloration

Water line stains and residues on your spa is cause by total dissolved solids precipitating from the water or by body oils building up in the tub. Remove with TUB CLEAN  ^ Top

9. No Chlorine or Bromine Reading

(A) Sanitizing demand not met. The hot tub water, especially during times of heavy use, becomes contaminated with bacteria, organic matter and oils, etc. These use chlorine and bromine as they are oxidized and until this demand is satisfied no sanitizer residue is left. DO NOT use your spa while sanitizer levels are below the recommended levels (chlorine 3-5 ppm or bromine 4-6 ppm)

(B) Test Kit reagents may be non-effective. These should be replaced each year. High sanitizer levels can bleach the color out of the reagents, making it appear that no sanitizer is present when there could be excess. Excess sanitizer can make the PH test to go purple. To correct, circulate the water.

(C) Algae consumes sanitizers quickly and may account for heavy demand.   ^ Top

10. Too Much Sanitizer

It may be harmful to use the hot tub if the sanitizer exceeds the recommended levels. To reduce, circulate the water with the cover off & air controls open for 15 to 30 minutes and retest the sanitizer level. Remove bromine floaters from water (if you are on this system) until levels have diminished to recommended level.  ^ Top
