Pure Enzymes for Pools (monthly treatment)

Easy Instructions

-Start with clean/clear water. Enzymes will not clear up dirty or green water.
-Add 1 bottle of Pure Enzymes for Pools (per 25k gallons) every month.
-Check & balance pH & alkalinity. Use Muriatic Acid to lower pH & Soda Ash to raise pH.
-Maintain .5 -1 ppm chlorine. This usually looks like: adding 2-3 high quality chlorine pucks to chlorine feeder & set to the lowest setting.
-Check pool for phosphates in the spring, mid-summer, and in the fall before closing. If you have a reading over 200 ppb, add a phosphate remover according to directions.
-When ready to close your pool, make sure water is clean & clear, add 1 bottle of Pure Enzymes for Pools for every 12,500 gallons, then close & cover. Your water will be crystal clear in the spring. Repeat pool opening/starting steps. (See Important Note below)
-In March, lift a corner of the pool cover and take a look at the water. You may need to add some liquid chlorine, if any debris has gotten into your pool water. When you open your pool for the season you should be good to go. Just follow the opening instructions.
-No other opening or closing chemicals are necessary. No shock needed. Keep filter clean.


Important Note
You need to have been using Waters Choice enzymes for at least 2 months to be able to close without traditional chemicals, ie. chlorine, algeacide, and a metal sequestering agent.

Weekly Maintenance

-Test your pH, alkalinity, and chlorine and make sure to keep these in the desired ranges.
-Vacuum and brush your pool.
-Check pressure on filter.

Monthly Maintenance
Add one bottle (or correct dosage per your pool size) of Waters Choice Pure Enzymes for Pools every month.

Closing your pool

Special Note

Your pool needs to have been running Waters Choice enzymes for at least 2 months to be able to close without traditional chemicals like chlorine, algaecide, and a metal sequestering agent

Cold climates

If you winterize, Waters Choice enzymes enable you to cut out opening and closing chemicals. Add one bottle of Pure Enzymes for Pools for every 12,500 gallons of water, balance pH & alkalinity, blow out your lines, and cover.

It is a good practice to check your water in March to see if it is starting to turn green, especially with mesh covers. If it is green, add a little chlorine, but don't add your enzymes until you are ready to take the cover off and open your pool.

Warm climate

If in the winter you turn off your heater and keep your equipment running, but do not use your pool, add ½ a bottle of Waters Choice Pure Enzymes for Pools every 6 weeks. Also, cut back on your chlorine.

Q -  STARTING/OPENING your pool with PURE ENZYMES for POOLS (monthly application)

• Start with clean, clear water.  Let your chlorine level drop to .5 - 1 ppm chlorine.
• Add 1 bottle of Pure Enzymes for Pools (up to 25k gallons).
• Balance & maintain pH & Alkalinity.
• Maintain .5 -1 ppm chlorine (usually by keeping 2-3 chlorine pucks in your chlorine feeder set on the lowest setting - adjust as needed).
• Add another bottle every month after that.
• 1 bottle treats up to 25,000 gallons of pool water.
• No other opening (or closing) chemicals needed.
• We do recommend checking for phosphates in the spring, mid-summer, & fall.  Phosphates left unchecked will result in algae growth.
• To close your pool, simply add 1 bottle of Pure Enzymes for Pools to clean, clear water and close up.  No other closing chemicals needed.

Q – CLOSING your pool with PURE ENZYMES for POOLS (monthly application)

• Add 1 bottle of Pure Enzymes for Pools to clean/clear pool water, then close it up.
• You do not need any other closing chemicals.

Q – Mid-winter check up

• It's a good idea to take a look under your pool cover about the month of February.
• If the pool water looks good, just close it back up.
• If the water has a tint of green, then add about .5 gallon of liquid chlorine.
• Check again the next day and add more if needed, until clear. Then close it back up.

Q – Is it safe to get into my pool immediately after adding Enzymes?

• Yes, enzymes are non-toxic and it is safe to use your pool immediately.

 Q – Calculating pool capacity in gallons

• Measure the Length x Width x Depth x 7.5 = your total gallons.
• You can also view our pool capacity chart on this page.

Q: Do I need to use a sanitizer in my swimming pool?

• Yes, keep your chlorine level between .5 - 1ppm.
• This amount is much lower than what you would use, if you were not using enzymes.
• With enzymes, this usually looks like keeping 2-3 high quality chlorine pucks in your chlorine feeder at the lowest setting.

Q: Do I need to use other chemicals in my pool?

• You will need to maintain the pH and alkalinity in the normal ranges.
• Use Muriatic Acid to lower pH and alkalinity in your pool.
• Use Soda Ash (sodium carbonate) to increase pH.
• Use Baking Soda (sodium bicarbonate), if you need to increase alkalinity.
• If you live in an area that has high phosphates you may need to add a phosphate remover.  We recommend checking for phosphates in the spring, mid-summer, and fall before closing.

Q: How to use Phosphate Remover

• If you have a phosphate reading of 200 ppb or more in your pool water, you will need to add a phosphate remover.
• First, backwash or clean your filter.
• Then calculate and add the amount of product needed according to the phosphate remover label.
• Run your filter system for at least 24 hours.
• If your filter pressure increases 10 psi over normal, clean and backwash filter.
• Let water sit for 12 hours then retest.
• Apply again, if needed, following the same directions.
• Vacuum pool floor.
• Reapply enzymes.

Q: Is it safe to backwash my pool filter onto my lawn? How often should I backwash?

• Yes, as long as your sanitizer (chlorine/bromine) level is below .5 ppm you can backwash directly onto the lawn.
• How often you back wash should not change much. Follow your manufacturer’s directions. You should usually backwash when your pressure gauge reading rises 5-7 lbs above your base line.

Q – POOL water has a tint of GREEN or algae

• Make sure to keep .5 - 1ppm chlorine in your water.
• Check for PHOSPHATES.  If more than 200 ppb, add a phosphate remover.
• Check for NITRATES.  Nothing we know removes nitrates.  If you have a reading of 10 ppm, drain ½ the pool & start over.  If at 20 ppm, drain entire pool & start over.
• Check for CYANURIC ACID (this is a build up from chlorine tablets). If over 300 ppm, then drain & clean (pressure wash) & refill.

Q – In POOLS, how much Muriatic Acid or Soda Ash do I add to adjust the pH?

• Check product packaging for directions
