6 Keys to Spa & Hot Tub Care

Water circulation is critical to ensuring even distribution of sanitizers, and also promotes filtration. As water circulates through the filter, it traps suspended particles.

Run the spa’s circulation every day to ensure clean, clear, soft water.



Because your spa filter traps many contaminants, cleaning it is very important. Many issues can occur when a filter is dirty or clogged.

To clean the filter, first spray off loose debris with a garden hose with a high-pressure nozzle. Then, use a cleaner to remove small contaminants that can get embedded. Filters should be cleaned every 4-5 weeks.



Regular cleaning preserves spa surfaces and prevents build-up. Use cleaning mitts and cleaner to remove the ring of oil and dirt that can build up at the waterline and eventually clog the filter.


Draining and Refilling

Over time, the water in your hot tub absorbs and dissolves minerals and chemicals. Based on how much you use your spa, when it starts to look dull, become foamy or develop an odor, it’s time to replace.

Stop in to Zagers for a professional spa water testing to determine if it’s time to replace the water.

This simple formula can help:

Spa gallons ÷ Daily bathers ÷ 3 = Days between draining

Example: 300 gallons ÷ 2 Daily Bathers ÷3 = 50 days

(Daily bather = one person in the spa for 15-30 minutes)



The two primary components that affect spa water quality are pH and sanitizer (either chlorine or bromine). When both are within the right range, water is comfortable, protected and clear.

Recommended Residual Levels

Bromine Residual using Brominating Tablets: 2-4 ppm
Bromine Residual using Brominating Concentrate: 3-6 ppm
Chlorine Residual using Chlorinating Concentrate: 3-5 ppm

Maintain pH between 7.4-7.6



Testing spa water ensures the proper chemistry! Simple test strips give you complete, easy test results that you can put into action.

The 3 essential chemicals to maintain are sanitizers, oxidation and water balance.

Daily Pool Maintenance

Keep your pool sparkling clean with routine, daily maintenance. It will be the envy of the neighborhood!

The 5 Keys to Basic Pool Care 


Pool water must be circulated properly in order to evenly distribute sanitizer chemicals.

When water is in motion, it’s harder for the algae and bacteria to grow, keeping the water cleaner. It also helps the pool filter to capture debris.

The best time to circulate the water is during the heat of the day. We recommend 8-10 hours daily.


A good filter is a critical component of a dazzling pool. It removes visible and microscopic matter.

Regularly backwash your filter to remove material trapped inside. In addition, a periodic chemical cleaning eliminates oils and embedded debris.


Algae and bacteria grow more easily in the areas of the pool without as much circulation. It’s important to brush the walls and vacuum the floor to remove debris that’s not trapped by the filter.


Test your pool water 2-3 times per week for pH and sanitizer levels. Because each swimming pool environment is unique, it’s important to test and adjust for your specific situation, and not just follow manufacturer guidelines.

Periodically through the season, bring a sample of your pool water to any Zagers location for in-depth testing and personalized recommendations.


Applying the right water treatment products, at the right time, will ensure brilliantly-sparkling results! It also provides a sanitary environment, balances the water to protect your pool.

Opening a Pool in the Spring

When the weather starts to get warm, your pool is ready to be opened!

There are several things that need to be done. The most important steps include:

– Remove the cover and lay it out flat to dry. Then, brush off the dirt and fold it. Store in a dry place, out of the sun.

– Fill with water until it reaches the middle of the skimmer opening.

– Check your pump, skimmer and filter to be sure they are working properly.

– Remove debris from the water with a skimmer and vacuum.

– Test and balance the water. Be sure to circulate the water for 24-48 hours before testing to ensure accuracy. Bring a sample of your pool water to any Zagers location – for in-depth testing and personalized recommendations.

– Add chemicals as needed, including chlorine or sanitizer, and shock the water to remove contaminants. Add a preventative algaecide to keep algae away.

– Run the pump for 24 hours upon opening, and then at least 8 hours a day after.
