Pool Enzyme Concentrate


16oz. Pool Concentrate
Treats about 10,000 gallons/year where pools are closed for winter.

Pool water is filled with organics, from sunscreen, sweat, urine, and debris from plants and trees. This puts a high demand on chlorine, which means you must use more. Waters Choice Enzymes break down the organics in your water, freeing up the chlorine to do what it does best. This allows you to use less chlorine which is so much better for you and your pool.
Enzymes are all natural and safe for your eyes, hair, and skin.


32oz. Pool Concentrate

Treats about 20,000 gallons/year where pools are closed for winter.

With our Enzymes it is important that you maintain proper water balance. You should clean your filter when the pressure increases 10-15 lbs. from the measurement when the filters are clean. Once you have been on our Enzymes for 2 months or more you can eliminate opening and closing chemicals.


1 Gallon Pool Concentrate

Waters Choice Pool Concentrate comes in 3 sizes; 16-ounce, 32-ounce, and 1-gallon so you can get the right amount that you need for your pool. All three bottles contain the same product just with differing amounts. Our Pool Enzyme Concentrate is added to your pool once a week at a rate of ½ ounce per 10,000 gallons of water except at opening and closing. When opening or closing add 2 oz. per 10,000 gallons 2 weeks in a row.
See charts below to determine how many gallons of water are in your pool.

In case you forgot how many gallons of water your pool holds here is a good formula:
For rectangular pools the formula is Width x Length x Average Depth x 7.5 = Gallons

The chart below may vary depending on the depth of your pool.

Benefits of Using Enzymes in Your Pool


Waters Choice Pool Concentrate

When opening your pool for the first time, or switching to Waters Choice, add 2 ounces per 10,000 gallons of our Pool Treatment week one and week two.

Check your pH and alkalinity—make sure they are in the recommended ranges.

Then check your phosphates. Phosphates are a food source for algae, so it is important to keep an eye on phosphates to prevent algae growth in your pool. If your level is above 200 parts per billion you will need to use a phosphate remover to get the level down. Test for phosphates 3 times per year - when you open, half way through the season, and just before you close. If you have phosphates in your fill or source water, you will need to test monthly.

Add small amounts of chlorine to bring your level to the minimum recommended rate.

Check your calcium hardness level and follow your manufacturer/builder recommendations.

Start with a clean filter. During the first month, keep an eye on your pressure gauge. Your level could climb faster than normal as the enzymes start cleaning up your water, pool walls, and plumbing.

Maintaining your pool:

Add 1/2 ounce per 10,000 gallons of water every week after the first two. Check your pH, Alkalinity, and chlorine level. Backwash or clean filter as needed.

What should my levels be?

pH: 7.2-7.6
Alkalinity: 80-120
Chlorine: No more than 1 ppm
Phosphates: No more than 200 ppb
Cyanuric Acid: No more than 100 ppm
Calcium: Follow your manufacturers/builder recommendation


Closing your pool:

When closing your pool, add 2 ounces per 10,000 gallons of water each of the two previous weeks before closing, check all other levels, then close. In warmer climates where the pools are not closed but are not used, add 1 ounce per 10,000 gallons of water every 6 weeks.

Second Year Opening:

Pools that are covered and shut down: Follow above directions for opening.

Pools that are left open with no heat: As the temperatures start to climb and use begins, go to the maintaining your pool directions.
