E-Z Pool Weekly Pool Shock and Algaecide, All in One Pool Treatment, 20 lb

APi E-Z Pool Concentrated Pool Blend is a granular, all in one weekly pool treatment made by APi Water in Jupiter, Florida, for above ground and inground swimming pools, including salt water pools. One dose a week oxidizes, controls algae, clarifies and conditions the water, maintains water balance, and inhibits stain and scale. It is a non-chlorine, oxygen based pool shock with a copper algaecide (EPA Reg. No. 70131-1), so one scoop is your chlorine-free pool shock, pool algaecide and pool clarifier. It is not a sanitizer, so keep using your chlorine, bromine or salt system.

What makes it different

• Triple chelated copper sulfate, a non-staining copper algaecide for swimming pools. Cheaper copper sulfate algaecides can discolor a pool's finish.
• Proprietary non-phosphate stain and scale control, stronger and longer lasting than competing products. It keeps calcium suspended, so the water feels softer.
• No fillers. The strongest formula available.
• The original, sold through pool professionals since 1996 and made in the USA.

Use it for

• Weekly care that keeps algae and cloudy water from starting: an all in one pool care solution in place of separate pool chemicals
• A weekly shock pool treatment for above ground and inground pools on chlorine, bromine, salt, mineral, ozone or UV
• Pools with automatic covers: APi says the cover can be closed 15 minutes after adding it to a circulating pool
• Closing the pool for winter

It is not for

• Clearing a pool that is already green or cloudy. Clear it first with chlorine or APi's Revive!, then start the weekly dose.
• Replacing your sanitizer
• Lowering calcium hardness

Weekly dose by pool size

Fill the 8 oz scoop that comes in the pail to the fill line, about half a pound. Double the first dose at the start of each season and for a new pool.

With a salt chlorine generator, mineral purifier, or ozone or UV system, use half the chart dose. In one application, never add more than 3 times the weekly dose. APi says you can swim 15 minutes after adding E-Z Pool to a circulating pool.

How long a pail lasts

Each pail holds about 2 scoops per pound: 10 in the 5 lb, 20 in the 10 lb, 40 in the 20 lb. Full weekly doses per pail:

The doubled first dose of the season uses one extra week's worth. At half dose on a salt, mineral, ozone or UV pool, a pail lasts twice as long.

Getting started

1. Have your water tested, then balance it: calcium hardness 350 ppm minimum, pH 7.2 to 7.6, total alkalinity 80 to 120 ppm.
2. Double the first dose to charge the water, at the start of each season and for every new pool.
3. Add E-Z Pool near a return jet, and keep adding sanitizer to your skimmer, feeder or floater as directed. With a salt chlorine generator, keep stabilizer at 50 ppm and adjust the generator setting to suit.
4. Repeat every week, and have your water tested monthly.

Closing your pool

Add 1 lb (2 scoops) per 5,000 gallons, straight into the pool or dissolved in a bucket and poured around the edge. No pre-treating or balancing is needed. It oxidizes contaminants and protects against algae through the winter, so spring openings are faster and the water is clearer.

Storing the pail

Keep the pail closed and dry, and never put a wet scoop back in it.
