Step 1: Clean the shell. The primary focus is to remove residue and contaminants from inside the tub. Clean the shell thoroughly using SeaKlear Thick Tile & Vinyl Cleaner according to label instructions.

Step 2: Clean the cover. Significant amounts of scum and chemical residue can accumulate on the spa cover. This can cause maintenance issues and lead to odor problems during use. To avoid this, when changing the water, the cover should be thoroughly cleaned using SeaKlear Thick Tile & Vinyl Cleaner.

Step 3: Clean the filter. To ensure peak filter performance, it is best to clean the filter weekly or after any heavy use. To clean, remove the filter cartridge and use SeaKlear Spa Filter Cleaner Spray according to label instructions. Every three months perform a deeper clean by soaking the cartridge in a solution of SeaKlear Spa Filter Cleaner & Degreaser overnight. Rinse thoroughly the next day and replace.


After filling the spa with water, complete the following steps:

Step 1: Treat for metals and minerals. No matter what type of water being used, SeaKlear Spa Metal Control should always be added immediately upon filling to prevent metal stains from source water.

Step 2: Treat for hard or soft water issues.

SOFT WATER has very little mineral content, which means the water will be aggressive to the equipment. If the water is untreated, it can cause damage to the pump, filter or heater. To prevent damage, use SeaKlear Spa Calcium Increaser according to label instructions immediately upon filling the tub. Do not attempt to balance soft water until it has been treated and the calcium hardness tests between 150 to 300 ppm.

HARD WATER contains a lot of minerals such as calcium and magnesium. This type of water will require special attention when balancing to account for excess minerals. If hard wateris untreated it can lead to the formation of scale on the tub surfaces and damage to the equipment. In hard water areas, use SeaKlear Spa Stain & Scale Control at least once per week.

Step 3: Balance pH and Total Alkalinity. When dealing with spa water, there are two main adjustments to be made, pH and total alkalinity.

Total alkalinity creates a buffer in the water so it can resist any acids that may be added to the spa. This is one of the most important water balance adjustments to be made. The pH cannot be properly adjusted if the total alkalinity is out of the suggested range. The recommended total alkalinity range in spas is 80 to 140 ppm. If the total alkalinity reading is LOW, use SeaKlear Spa Alkalinity Up as follows:

1. Add 1 oz. (2 Tbsps) to spa water with circulation on.

2. Allow water to circulate for 30 minutes.

3. Retest water and repeat steps 1 & 2 until the desired level is reached. Note: For best results, dissolve granular products first by adding to a small plastic pail filled with water.

pH is a measurement of the acids or bases in the water. A low pH indicates the water is primarily acidic. A high pH means the water is more base or alkaline. Both total alkalinity and pH can be checked by using a recommended test strip for spa use.

If the pH is above 7.8, lower both the total alkalinity and pH by using SeaKlear Spa pH Reducer as follows:

1. Turn on the air blower of the filter system and add 1 ounce of SeaKlear Spa pH Reducer.

2. Retest the water after 30 minutes.

3. Follow steps 1 & 2 until pH and total alkalinity is in range.

Note: Do not add more than 1 ounce of product at a time. Always wait 30 minutes between doses.

If the pH is below 7.2, raise it by using as follows:

1. Turn on circulation jets and add 1 oz. of SeaKlear Spa pH Increaser for every 100 gallons of spa water.

3. Retest water after 30 minutes

You can also adjust and stabilize the pH by using SeaKlear Spa pH Steady using the same steps as pH instructions above. Note: SeaKlear Spa pH Steady is not recommended for areas of hard water where the calcium hardness is over 300 ppm.


Once the water is properly balanced (see second page), begin the simple SeaKlear Chemical Start-Up Program.

Step 1: Shock spa water. Shocking with a strong oxidizer clears the water of organic materials, eliminates odor and prepares the spa for sanitization. Once the water has been tested and adjusted, shock with SeaKlear Spa Chlorine Free Shock Oxidizer.


pH 7.2 - 7.8 PPM SeaKlear Spa pH Reducer, pH Increaser
Total Alkalinkity 80 - 150 PPM SeaKlear Spa Alkalinity Up
Calcium Hardness 150 - 300 PPM SeaKlear Spa Calcium Increaser
Chlorine 1.0 - 3.0 PPM SeaKlear Spa Sanitizing Granuals

Add the shock over the top of the water with the circulation jets on. Leave the cover off of the tub for one hour.

Step 2: Floc. Floccing removes small particles of dirt and oil that cause cloudy water and scum lines. An initial dose of SeaKlear Spa Natural Clarifier should be added. If the fill water is extremely cloudy, or additional performance is desired, use SeaKlear Spa PRS.

Step 3: Sanitize. If using a CHLORINE program, turn on the circulation system. Scatter 3 teaspoons of SeaKlear Spa Sanitizing Granules per 500 gallons of water. Always use a clean, dry, plastic scoop. Maintain 3 ppm free available chlorine (FAC) while the spa is in use. Add product as needed.

If using a BROMINE program, add 1⁄2 ounce of SeaKlear Spa Sodium Bromide per 100 gallons of water. Let water circulate for 30 minutes. Introduce SeaKlear Spa Brominating Tablets with the use of a floating tablet feeder or automatic brominator installed on the spa equipment. Adjust tablet feeder or brominator to obtain an active bromine residual of at least 3 ppm. Maintain the spa by adding three tablets as needed to maintain an active bromine residual of 3 ppm at all times.

Your spa may be equipped with an automatic device known as a bromine generator that creates bromine by using electrolysis. They require an increased amount of sodium bromide to operate. When working with a spa that uses this generator, use SeaKlear Spa Phosphate Remover weekly at a rate of 1 ounce for up to 500 gallons of water.
