The Basics of our Algae Free Guarantee: algae-free-guarantee-logo

  • Algae should not grow if you properly take care of your pool
  • Algae WILL NOT grow if you use Bioguard products and follow one of our proven pool care systems
  • Algae can’t grow because you’ll get FREE product to kill it even if it ever does

Easy right?!

How to qualify for the Algae Free Guarantee in 4 simple steps:

Before any pool can be considered for the Algae Free Guarantee it first must be 100% free of algae.  Clear up problems with an EPA registered algaecide such as Bioguard Banish and then maintain your pool in such a manner:


Many pool owners to not fully comprehend the importance of constant and consistent pool maintenance.  Adding product when the pool needs it, not just when it’s convenient, is imperative to achieving not just an algae-free pool, but also a problem-free pool.

Sanitize: Keep a free available chlorine (FAC) between 1.0 ppm and 3.0 ppm at all times.  The ideal method of delivery FAC is to use Bioguard Silk Smart Sticks fed through the pool’s surface skimmer.  When applied according to label directions, they slowly dissolve and provide a constant and consistent level of FAC in the pool for the entire week.

Weekly Shock:  This will remove contaminants that are introduced through swimmers and the environment.  A weekly shock oxidizes contaminants and leaves water sparkling clear.

Preventative Algaecide: Adding once a week will stop algae in its tracks even before it is a visible problem.



Poor filtration and/or inadequate circulation cause more problems every year than poor water chemistry.

Regardless of your preference, 10-12 hours during the daylight hours should be viewed as the minimum time for circulation and filtration.  Routine cleaning of the skimmer basket, pump hair & lint basket, and routine cleaning of the filter media (sand, cartridge, or DE) is an essential part of the requirement.

The life span of any filter media will increase dramatically with routine cleaning, and result in hundreds of dollars saved on replacement media and/or the problems that result from poor or inadequate filtration.

If the pool routinely develops an oily waterline, it is safe to assume the filter must be cleaned to remove the oils inside the filter.  The average chlorine-treated pool should be chemically cleaned with Bioguard Kleen-It or Strip Kwik every 2 months during the swimming season AND once prior to the winter months.


Properly balanced water not only saves money, but allows you to monitor water quality issues that could otherwise cause substantial damage to the pool’s surface and equipment.

By using our ALEX Water Analysis software, we can perform comprehensive testing to easily and effectively monitor your pool’s water quality.  ALEX can store an unlimited number of water analysis for later reference.  Water analysis must be performed monthly at a Zagers’ location.

It is best to bring in a water sample prior to any chemical treatment in order to be sure you receive the best and most efficient recommendations.  All Algae Free Guarantee participants are given a water sample bottle and instructions on how to obtain the best sample of water for testing.  Make sure the sample is taken in an area of the pool that is away from a return inlet and that the sample is taken from at least 18″ below the surface of the water.

STEP 4: MAINTAIN BIOGUARD OPTIMIZER PLUS AT 30 – 35 PPMOptimizer Plus - small image

Optimizer Plus provides enhanced clarity and water comfort and is also an EPA-registered algae suppressant.

Optimizer Plus suppressed the growth of algae by inhibiting the algae’s ability to metabolize carbon dioxide.  You will find that problem pools that routinely experience algae growth in July will now be remarkable clear and algae free.

The water is given it’s fantastic clarity and brilliance due to the fact that Optimizer Plus increases the solubility of calcium, a primary contributor to water cloudiness.  The water will become so comfortably clear that swimmers will no longer complain of irritated eyes or itchy skin.  The softened feel of the water is a result of the mineral conditioning.

Optimizer Plus is added to fresh pool water once, only needing to be re-added if a large amount of water is splashed out or drained from the pool.
