Closing your pool for the season is about more than covering it and protecting the equipment from freezing temperatures. What happens in the water during the months your pool is closed can have a major impact on what you find when you uncover it in the spring.

That’s why we recommend adding a double dose of Waters Choice Enzymes before closing your pool for the season.

Giving your pool an extra dose of enzymes before winter provides additional enzyme activity to help manage the organic contaminants that remain in the water while your pool is closed.

1. Helps Break Down Organic Contaminants

Even a clean-looking pool contains organic material.

Throughout the swimming season, pool water accumulates sunscreen, body oils, lotions, pollen, insects, leaves and other organic contaminants. Some of this material can remain in the water when you close your pool.

Waters Choice enzymes help break down these organic contaminants. Adding a double dose before closing gives your pool an extra supply of enzymes to continue working on that organic load as you prepare the pool for its months of downtime.

2. Helps Reduce the Organic Load Over Winter

Once your pool is covered, you are no longer maintaining it the same way you do during swimming season.

That makes proper preparation especially important.

Organic material left behind can contribute to unwanted buildup and create conditions that make spring cleanup more difficult. Starting the winter with an extra dose of Waters Choice enzymes helps reduce that organic load before the pool sits unused for an extended period.

3. Helps Keep Water Cleaner and Clearer

Tiny organic particles and contaminants can contribute to cloudy or dull-looking water.

Enzymes work by breaking down organic waste that would otherwise remain in the pool. Starting the off-season with a double dose can help maintain cleaner water while the pool is closed and give you a better starting point when it is time to open again.

4. Can Make Spring Opening Easier

Nobody wants to remove the pool cover in spring and discover a major cleanup project.

The better condition your water is in when the pool is closed, the easier your spring opening can be.

Using a double dose of enzymes as part of your closing routine helps address organic contaminants before winter, which may mean less organic buildup to deal with when swimming season returns.

5. Supports Your Overall Pool-Care Routine

Enzymes are designed to complement your regular pool-care program by targeting organic contaminants that traditional sanitizers and filtration systems must otherwise handle.

Reducing that organic load can help your pool-care system work more efficiently and helps you maintain cleaner, better-looking water.

How to Use Waters Choice When Closing Your Pool

Before closing your pool for the season:

1. Make sure water is clean & clear
2. For Pure Enzymes for Pools users, add 1 bottle of Pure Enzymes for Pools for every 12,500 gallons
3. For Pool Concentrate users, add 2 oz. per 10k gallons 2 weeks in a row
4. Close and cover your pool
5. Complete the remaining winterization steps required for your pool, plumbing and equipment.

Waters Choice enzymes are an addition to proper winterization, not a replacement for it. Always follow the appropriate procedures for balancing your water, protecting plumbing and equipment, lowering the water level when required and preparing your specific pool for freezing temperatures.

Give Your Pool a Head Start on Spring

A little extra preparation in the fall can make a significant difference when it is time to open your pool again.

By double dosing your enzymes, you give the enzymes additional capacity to work on the organic material left behind from the swimming season and help your pool go into winter in the cleanest condition possible.

The goal is simple: less organic buildup over winter and an easier start when spring arrives.
