Carefree's Weekly Water Test

Use the table below to perform your weekly water tests. For more information review the water balance section.

For the best water clarity results, test your water with a high range test kit or “5-in-1” Water Test Kit once per week as follows:

 

 
   
 
Water Test #1 Water Test #2 Water Test #3 Water Test #4
For Chlorine/Bromine Purity Systems Total Alkalinity Test Total pH Test Calcium Hardness Test
Ideal Range: Chlorine 1.5-2PPM Ideal Range: 90-120PPM (9-12 drops) Ideal Range 7.4-7.6 Ideal: 150PPM
If the results are LOW add Chlorine Concentrate. This chemical should be added after all water tests have been completed and all other balancing chemicals have been added If the results are LOW (below 90PPM or 9 drops) raise alkalinity with Total Alkalinity Increaser product. If the results are LOW, retest total alkalinity.  If results show that total alkalinity is within range, raise pH with pH Increaser product. Use chart on back of bottle for instructions and quantities.  
If chlorine results are HIGH, add 2-5 drops of Chlorine Neutralizer reagent #4 when testing pH and total alkalinity. If total alkalinity results are HIGH (above 170PPM or 17 drops) retest to confirm results and contact Carefree Spas for a water test discussion. Hint: 1 Tablespoon of Total Alkalinity Increaser per 200 gallons = 10ppm. Hint: When testing Total Alkalinity use 2-4 drops of Reagent #4 (Chlorine Neutralizer) instead of directions that call for 1 drop if chlorine/bromine is high. If results are HIGH add pH Decreaser. Hint: Only add 1 Tablespoon per 200 gallons at a time. Retest after a few hours. Hint: When testing pH use 2-4 drops of Reagent #4 (Chlorine Neutralizer) instead of directions calling for 1 drop if chlorine/bromine is high. Upon drain and refill, bring water sample to  for analysis and recommendations.
Typically shock spa water once per week. Hint: average shock is 1 teaspoon of Chlorine Concentrate per 100 gallons. Correct total alkalinity only when sanitizer (chlorine/bromine) level is normal or below normal.  Correct alkalinity before attempting to correct pH. Correct total pH only when sanitizer (chlorine/bromine) level is normal or below normal.
