USEFUL INFORMATIONS

SYMPTOM	PROBABLE CAUSE	UNDERLYING REASON	TO RECTIFY	SOLUTION
CLOUDY WATER	Build up dirth and pollution	Insufficient chlorine or poor filtration	Backwash fitler then super chlorinate 10 ppm of free chlorine. Add flocculant to polish water.	CLARIS Precipitating hth or CLARIS Chlorine Granular CLARIS Anti-algae CLARIS Transparent
	Start of algae growth	Insufficient levels of chlorine Prevent recurrence	Superchlorinate. Backwash filter after 24 hours. Maintain chlorine level between 2 - 3 ppm. Prevent to growth algae.	hth or CLARIS Chlorine Granular CLARIS Anti-algae CLARIS Control
	Chlorine ineffective Ineffective filtration Dispersed grains	Check stabilizer level Old filter blocked Sedimented salts because of high pH or Alkalinity	Add fresh water and chlorinate by chlorine. Check alkalinity and filter cartridge. Adjust pH and alkalinity.	Advice your hth swimming pool service CLARIS pH -
UNPLEASANT WATER. SORE EYES, THROAT. ITCHING SKIN	High combined chlorine Detergents from cleaning compounds in pool water Water too acidic or alkaline	Breakpoint chlorination not being achieved Reaction between chlorine and detergent pH too low or too high	Superchlorinate. Use biodegradable detergents. Bring pH to within parameters recommended.	hth CLARIS Pak CLARIS pH - / pH +
CHLORINE LEVEL DIFFICULT TO MAINTAIN	In outdoor pools sunlight destroys chlorine Built up pollutants or chlorine not getting to pool.	Chlorine is not stabilized Insufficient chlorination Blockage or mulfunction of chlorine dosing system	Use stabilizator or stabilized chlorine. Superchlorinate. Raise the disinfectant. Check injector, pump and auto controller.	CLARIS Stabilizator CLARIS Chlorine Granular CLARIS Chlorine Granular CLARIS Anti-algae
APPARENT INABILITY TO GET CHLORINE READING ON TEST KIT IN SPITE OF CHLORINE ADDITION	Chlorine level may be too high	Too much chlorine can spoil test tablets	De-chlorinate. If very high reduce with chemicals or dilute.	Advise your swimming pool service
pH TOO LOW	Too much pH corrective getting to pool	Auto control out of calibration or mulfunction	Check out pH corrective system and auto control.	CLARIS pH +
pH TOO HIGH	Insufficient pH corrective being added or applied incorrectly or high alkalinity	Possible malfunction of system	Check out auto control/ calibration. Maintain pH between 7,2 - 7,6 Reduce alkalinity to 80-120 ppm.	CLARIS pH - CLARIS pH -
pH LOCKED	High levels of alkalinity	Topping up from mains water can increase alkalinity in hard water areas	Check pH. Reduce alkalinity to 80-120 ppm.	CLARIS pH - Advise your swimming pool service
DIRTH ON POOL WALL AT WATER LINE	Built up body fats, sweat, sun tun oil and cosmetics	Irregular cleaning of surfaces	Clean with biodegradable chemical	CLARIS Pak
pH LEVELS ERRATIC	Insufficient bicarbonates to buffer pH	Low total alkalinity	Add bicarbonate to raise alkalinity to 80-120 ppm.	CLARIS pH + Advise your swimming pool service
POOL WALLS FEEL SLIMY	Algae growth	Insufficient chlorination and pool wall brushing	Superchlorinate to kill algae. Sweep or vacuum debris. Prevent re-occurence with algicide.	hth or CLARIS Chlorine Granular CLARIS Anti-algae CLARIS Control
ROUGH SCALE FORMED ON POOL SURFACES AT WATER LINE	Water out of “balance”	Ratio of calcium hardness to total alkalinity incorrect	Check levels of pH, Alkalinity and calcium are within parameters recommended	CLARIS Pak
SHARP EDGES AROUND TILES	Grout being leached by water	Mains water too soft	Regrout the pool. Increase calcium levels to min. 350 ppm and maintain. Consider change of sanitizer (calcium hypochlorite) to prevent reoccurrence.	hth
INEFFECTIVE FILTRATION	Sand Filter Is sand level correct? NO... YES... Is air being sucked into the fitler?	Sand is not enough for filtration Blocked filter or filtration needs assistance Air will affect the efficiency of the fitler	Renew or top up sand. Backwash filter and use flocculant. Check all joints pre-pump, gaskets on strainer pots and look for air being drawn into the system.	Advise your swimming pool service CLARIS Precipitating
INEFFECTIVE FILTRATION	Cartridge Filter NO... YES... Is the cartridge clean and a good condition?	Filter is not filtering. The service of the filter is necessary	Change cartridge. Use coagulant/flocculant and backwash.	Advise your swimming pool service CLARIS Precipitating
DISINFECTANT IS USED TOO MUCH	Little cyanuric acid	Preventation of chlorine from U.V. becomes less	Put cyanuric acid. ( 40 - 60 ppm )	CLARIS Stabilizator
	High Heat	Speed up chlorine reactions	Superchlorinate.	CLARIS Chlorine Granular
	Too many swimmer, too much fouling	High oxidation demand appears.	Superchlorinate.	CLARIS Chlorine Granular
LIGHTER HAIR COLOUR	Making wrong test	High chlorine ( < 15 ppm )	Sodium sulfate or sodium bisulfate.
GETTING WHITE SWIMMING SUITS	Old test tablets	High chlorine ( < 15 ppm )	Use sodium tiosulfate.
SCALE FORMATION IN SWIMMING POOL WALLS, PIPES, FILTERS, HEATINGS	High pH	Calcium carbonate mixture is over	Take down pH with acid.	CLARIS pH -
	High levels of alkalinity	Calcium carbonate mixture is over	Take down alkalinitiy with acid	CLARIS pH -
