Winter Saltwater Hot Tub Maintenance: A Comprehensive Guide

Winter weather can leave hot tub owners with a variety of questions and concerns about their saltwater hot tub maintenance. Freezing temperatures can bring damage to equipment while milder climates can affect the salt levels that impact chlorine production. We’ve put together this all-encompassing guide for saltwater hot tub maintenance to help navigate saltwater spa needs throughout the winter.

1. Test Chemical Levels Regularly

The key to winter saltwater hot tub maintenance is frequent testing. It’s important to test for chlorine levels, pH levels and total alkalinity using a reliable test strip or kit. If any of these are out of balance, it’s time to take corrective action immediately. Saltwater chlorination may be less effective once water temperatures drop below a certain point, so if a hot tub is not being used regularly during cooler weather, spa users should make special note to keep a check on chlorine levels. This will help to ensure that bacteria and other microorganisms are effectively eliminated.

2. Monitor Water Clarity

Hot tub water clarity is indicative of how well the water is being filtered and circulated. It’s important to check the level of visibility in spa water regularly, paying special attention to any particles that might be in it or if there is a presence of foam or bubbles on the surface. If there is any change in clarity, it’s important to check the filter and adjust the clarifier levels. Owners should clean or replace filters as needed, and make sure the pump is running efficiently before adding more sanitizer or shock treatments.

3. Regular Shock Treatments

Shock treatments are a key part of saltwater hot tub maintenance during winter because they help break down oils, soaps and other contaminants that build up in water. Hot tub users should shock their spas at least once a week during the wintertime to maintain clarity and keep chemical levels balanced. It’s important to maintain a chlorine residual of at least 2 parts per million throughout the winter months.

4. Check Water Levels

During winter, owners should check water levels on a regular basis for evaporation. Water levels should be kept between the mid-level and max line to ensure proper circulation, filtration and heat transfer. If hot tub water levels drop too far below the mid-level line, it could result in damage to pumps and other components. Owners should keep an eye on water levels during winter and add additional water as needed.

5. Protect Equipment

To protect hot tub equipment, owners should consider investing in a hot tub cover and making sure the equipment is insulated wherever possible. This can help prevent freezing temperatures from damaging pumps, motors and other components. It’s also important to unplug the hot tub when not in use and consider a filter timer to prevent overuse of the hot tub’s filtration system.
