Spa Troubleshooting

Possible Cause

Solution

Preventative Maintenance
Cloudy, Dull Water
pH Balance and Total Alkalinity Levels Incorrect Test pH and total alkalinity. Adjust levels using Rendézvous™ pH Up, Rendézvous™ pH Down or Rendézvous™ Alkalinity Up. Lock in the pH level between 7.2 and 7.8 range with Rendézvous™ pH Magic® water balancer until spa is refilled. When the spa is refilled, add Rendézvous™ pH Magic® water balancer (1.3 kg/2,000 L) to lock in the correct pH level.
Excessive Organic Contaminants Shock treat with Rendézvous™ Activate™ granular to control bacteria and algae. Treat with GLB® Natural Clear™ clarifier to break down oily water. Add a dosage of Rendézvous™ Activate™ granular (60 g/1,000 L) to shock treat and regenerate the bromine sanitizer. Add GLB® Natural Clear™ clarifier (15 ml/1,000 L) weekly to prevent oily build-up.
Dissolved Chemical Solids in Water Use Rendézvous™ Spa Clarifier to help remove small particles. Once a week or whenever the spa water appears cloudy, add Rendézvous™ Spa Clarifier (30 ml/1,000 L).
Calcium Too High (Hard Water) Use Rendézvous™ Protect Plus™ sequestering agent regularly. Replace some of the spa water. Add Rendézvous™ Protect Plus™ sequestering agent (30 ml/1,000 L) weekly to inactivate dissolved minerals in the water.
Cloudy, Green Water
Low Alkalinity Level Add Rendézvous™ Alkalinity Up. Test water ofren and maintain a total alkalinity level of 100-120 ppm.
Low Sanitizer Level Test and adjust sanitizer level, shock with Rendézvous™ Activate™ granular. Shock treat with Rendézvous™ Activate™ granular (125 g/1,000 L). Maintain a sanitizer level of 3-5ppm at all times.
Brown Water
High Iron or Manganese Content Use Rendézvous™ Protect Plus™ sequestering agent. Use Rendézvous™ Protect Plus™ sequestering agent (30 ml/1,000 L) to suspend and inactivate minerals that cause water discoloration.
Clear, Green Water
High Copper Content Use Rendézvous™ Protect Plus™ sequestering agent. Use Rendézvous™ Protect Plus™ sequestering agent (30 ml/1,000 L) to suspend and inactivate minerals that cause water discoloration.
Chalky, White Scale Deposits
Mineral Deposits in Water Use Rendézvous™ Protect Plus™ sequestering agent. Check water balance and adjust as needed. Use Rendézvous™ Protect Plus™ sequestering agent (30 ml/1,000 L) to suspend and inactivate minerals that cause water discoloration.
Skin and Eye Irritation
Excessive Organic Contaminants Shock treat with Rendézvous™ Activate™ granular.  Shock treat with Rendézvous™ Activate™ granular (125 g/1,000 L) weekly.
pH Too Low or Too High  Test pH and alkalinity. Adjust levels using Rendézvous™ pH Up or Rendézvous™ pH Down. Use Rendézvous™ pH Magic® water balancer (1.36 g/2,000 L) to lock in correct pH levels.
Odor
Excessive Organic Contaminants Shock treat with Rendézvous™ Activate™ granular. Use GLB® Natural Clear™ clarifier to prevent oily build-up. Shock treat with Rendézvous™ Activate™ granular (125 g/1,000 L) at least weekly to destroy organic contaminants.
Foaming
High Concentration of Chemicals, Body Oils, Cosmetics and Other Contaminants Due to Heavy Bather Load Use Rendézvous™ Foam Out. Shock treat with Rendézvous™ Activate™ granular. Shock treat with Rendézvous™ Activate™ granular (125 g/1,000 L) at least weekly to destroy organic contaminants. Drain and refill spa at least every 90 days.
Calcium Hardness Too Low Adjust calcium hardness to raise level. Test and adjust to maintain recommended water balance levels.
Pitting of Metal Fixtures or Plaster Spa Surfaces
pH and/or Total Alkalinity Too Low Adjust total akalinity and pH balance of water with Rendézvous™ pH Up and Rendézvous™ Alkalinity Up. Test and adjust as necessary to maintain pH level of 7.2-7.8 and total alkalinity of 100-120 ppm. When the spa is refilled with fresh water, add Rendézvous™ pH Magic water balancer (1.36 kg/2,000 L) to lock in the correct pH level. 
Scum Deposits on Waterline
Body Oils and Dirt Use GLB® Natural Clear™ clarifier regularly to reduce scum and odor-causing oils, lotions and organic materials in the water.  Add GLB® Natural Clear™ clarifier (15 ml/1,000 L) once a week to remove scum lines and protect the filter from oily build-up and clogging.
