Calculate the size of your spa

Knowing the size of your spa is important. So if you are not sure how many gallons of water are in your spa, use the appropriate calculator below to get an approximate idea.

Square/Rectangle Spa

Round Spa

Oval Spa

Step 1. An Introduction

To insure a clean spa with beautiful clear water, there are three basic areas of maintenance you should be familiar with. Those are covered in Steps 2, 3, and 4 listed below. Steps 4, 5, and 6 put the previous steps together in an easy to use “program” resulting in clean good looking water with minimum effort.

Step 2. Shock & Sanitize

There are two types of water care products which always need to be added to maintain healthy and great looking water. Those two products types are sanitizers and oxidizers. Oxidizers are often referred to as Shock.

Sanitizers, which need to be added consistently, control and destroy germs and other unwanted bacteria from the water. Oxidizers, added at least weekly, remove the buildup of materials we introduce to the water, like personal care products and sweat. Additionally, oxidizers revitalize sanitizers in water and prevent water from emitting an unpleasant odor.

SpaPure Bromine Tabs The easiest way to introduce sanitizer to spa water.

SpaPure Granular Chlorine Strong, effective, long lasting, and completely soluble sanitizer.

SpaPure Oxidizing Shock Fast dissolving and odor free shock that does not use chlorine or bromine.

Step 3. Water Balance

Maintaining proper water balance will ensure maximum results from your sanitizer and comfortable water. If you are filling your spa for the first time you should have your water tested by your authorized SpaPure dealer. You dealer will analyze Total Alkalinity, pH, Calcium Hardness and a few other parameters important to short and long term spa care. As the spa is being used during the year, the water should be tested at least a couple of times weekly, to ensure that these factors are within their appropriate ranges. If any of these balance factors are off:

Use SpaPure Alkalinity Increaser to elevate alkalinity into the range of 100-120 ppm.

Adjust pH to 7.2-7.6 by using SpaPure pH Up or SpaPure pH Down.

SpaPure Hardness Increaser will raise water hardness to the desired range of 150-250 ppm.

Step 4. Cleaning

A spa filter works hard to remove material from your water, most of which is too small to see with the naked eye. Since the filter is constantly collecting material, light to moderately used spas should have their filters cleaned and degreased monthly with SpaPure Filter Cleaner . Looking to avoid cleaning the filter? Regular additions of SpaPure EZ Enzyme will effectively extend the time between cleanings!

The natural breakdown of cleaning products and the build-up of oils from your own skin will eventually make the spa water less pleasant than the day it was first filled. For the ultimate spa experience, your home spa should be drained and refilled every three months. Between refills, clean the spa surface with SpaPure Spa Cleaner . This cleaner, safe for all surfaces, will help keep your spa looking and feeling its best for years

Step 5. Ideal Ranges for Residential Spas

7.2 - 7.6

Total Alkalinity
100-120 ppm

Calcium Hardness
150-250 ppm

3.0-5.0 ppm

Free Chlorine
1.0-3.0 ppm

0 ppm


These steps are for those freshly filling a new or an existing spa.

1) As the spa is filling add SpaPure Simply Soft to the spa. This will make water care a breeze and keep water looking spectacular.

2) Shortly afterwards, add SpaPure Stain & Scale Preventer to the spa. This will prevent water issues such as scaling and staining.

3) Once the spa is filled and well circulated, balance the spa water. Specifically pH, total alkalinity, and calcium hardness

4) Add a sanitizer to the spa. When using bromine, start by adding SpaPure Brom Bank to the spa. Shortly afterwards, add SpaPure Bromine Tabs to the spa in an appropriate tablet dispenser. When using chlorine add SpaPure Granular Chlorine directly to the spa to achieve appropriate sanitizer levels.

5) Shock the spa. If your recently purchased a spa or have not filled your spa in some time use SpaPure Granular Chlorine.

Step 7. Routine Spa Care

Check your spa periodically to insure that the spa is circulating at least four hours a day. Without circulation, no matter how many water care products you add to the spa, the water will turn cloudy, smelly, or worse.

Weekly care should include three steps:

Apply SpaPure EZ Enzyme to maintain water clarity

Apply SpaPure Stain & Scale Preventer to prevent scale buildup on surfaces and equipment

Shock the spa using SpaPure Oxidizing Shock or SpaPure Multi Shock Extra
