Spa & Hot Tub Troubleshooting

Possible Cause: Total alkalinity or pH out of balance

Solution: Test water and adjust total alkalinity and pH as necessary using Sirona^™ Spa U or Sirona^™ Spa Down.

Preventative Maintenance: Maintain a pH of 7.2 – 7.8 and total alkalinity of 80 – 120 ppm.

Possible Cause: Chloramines or excessive organic contaminants

Solution: Shock oxidize with Sirona^™ Activate Granular non-chlorine shock oxidizer. If using the Sirona^™ Simply system treat with Sirona^™ Simply Oxidizer non-chlorine shock oxidizer. Check and adjust sanitizer level.

Preventative Maintenance: Use Sirona^™ Activate Granular non-chlorine shock oxidizer weekly.

Possible Cause: A buildup of bacteria, debris or other contaminants.

Solution: Shock oxidize with Sirona^™ Activate Granular non-chlorine shock oxidizer. Check and adjust sanitizer level.

Preventative Maintenance: Use Sirona^™ Activate Granular non-chlorine shock oxidizer weekly.

Possible Cause: Water out of balance

Solution: Check water balance with Sirona^™ Test Strips and adjust as necessary.

Preventative Maintenance: Keep your spa water balanced by making sure it is within the following recommended ranges: pH 7.2-7.8, total alkalinity 80-120 ppm and calcium hardness 150-400 ppm.

Possible Cause: High mineral content in water

Solution: Treat spa water with Sirona^™ Defend (2 fl. oz. per 800 gallons).

Preventative Maintenance: Use Sirona^™ Defend weekly to prevent scale formation, aid in the removal of existing scale and to help prevent precipitation of dissolved solids in spas or hot tubs.

Possible Cause: Oils, lotions and detergents from spa users have caused buildup

Solution: Clean scum line with a spa surface cleaner. Use 1 fl. oz. Sirona^™ Natural Clear Enzyme Clarifier per 250 gallons of water.

Preventative Maintenance: Use Sirona^™ Natural Clear Enzyme Clarifier weekly.

Possible Cause: High iron or manganese content

Solution: Add Sirona^™ Prevent to sequester minerals in the water. Check pH level.

Preventative Maintenance: Test pH and total alkalinity and maintain proper levels. Sirona^™ Prevent should be used each time the spa is filled.

Possible Cause: Dissolved copper or iron in spa water

Solution: Add Sirona^™ Prevent to sequester minerals in the water. Check pH level.

Preventative Maintenance: Test pH and total alkalinity and maintain proper levels. Sirona^™ Prevent should be used each time the spa is filled.

Possible Cause: Total alkalinity or pH out of balance

Solution: Test water and adjust total alkalinity and pH as necessary using Sirona^™ Spa Up or Sirona^™ Spa Down

Preventative Maintenance: Maintain a pH of 7.2 – 7.8 and total alkalinity of 80 – 120 ppm.

Possible Cause: Dirty filter

Solution: Use Sirona^™ Spray & Rinse Filter Cleaner on a monthly basis or deep clean with Sirona^™ Filter Cleaner.

Preventative Maintenance: Clean filter with Sirona^™ Filter Cleaner on a monthly basis.

Possible Cause: Calcium too high

Solution: Treat spa water with Sirona^™ Defend (2 fl. oz. per 800 gallons).

Preventative Maintenance: Use Sirona^™ Defend weekly to prevent scale formation, aid in the removal of existing scale and to help prevent precipitation of dissolved solids in spas or hot tubs.

Possible Cause: Excessive organic contaminants or lack of sanitizer

Solution: Shock oxidize with Sirona^™ Activate Granular non-chlorine shock oxidizer. If using the Sirona^™ Simply system treat with Sirona^™ Simply Oxidizer non-chlorine shock oxidizer. Check and adjust sanitizer level.

Preventative Maintenance: Use Sirona^™ Activate Granular non-chlorine shock oxidizer weekly.

Possible Cause: Buildup of unfilterable material

Solution: Use Sirona^™ Spa Clarifier (2 fl. oz. per 800 gallons). Its unique polymer action neutralizes and removes dirt, soap, oily films and suspended particles to create clean, fresh water.

Preventative Maintenance: Use Sirona^™ Spa Clarifier weekly.

Possible Cause: Low sanitizer level

Solution: Shock oxidize with Sirona^™ Activate Granular non-chlorine shock oxidizer. If using the Sirona^™ Simply system, treat with Sirona^™ Simply Oxidizer non-chlorine shock oxidizer. Check and adjust sanitizer level.

Preventative Maintenance: Maintain a sanitizer level of 3-5 ppm.

Possible Cause: Buildup of body oils, cosmetics and detergents from bathers

Solution: Add Sirona^™ Foam Out. Shock oxidize with Sirona^™ Activate Granular non-chlorine shock oxidizer. If using the Sirona^™ Simply system, treat with Sirona^™ Simply Oxidizer non-chlorine shock oxidizer. Check and adjust sanitizer level.

Preventative Maintenance: Use Sirona^™ Activate Granular non-chlorine shock oxidizer weekly.

Possible Cause: Calcium hardness is too low

Solution: Add Sirona^™ Calcium Booster to obtain 150-400 ppm calcium level in the water.

Preventative Maintenance: When adding make-up water or freshly filling the spa, have the calcium level tested.

Possible Cause: Large amount of total dissolved solids

Solution: Change spa water.

Preventative Maintenance: Drain and refill water at least once every 90 days.
