Comparing Chlorine, Bromine, Soft Swim® (biguanides), Ionizers (Nature2® or Frog®) & Mineral Springs® (salt/chlorine generation)

Here's a quick table showing the pros & cons of the various sanitizing systems for swimming pools.  We hope this information helps you make a good, informed decision as you choose which system is right for your particular situation.

Pool care is definitely not "one size fits all." There are many factors to take into consideration as you protect the pool, its equipment and most importantly, your family & friends who will be swimming & playing in it.

1. Nature2
® or Spa Frog® Spa Care using our recommended systems including BioGuard® Easy Shock & Swim & Optimizer Plus
2. Only Chlorine, Bromine and Biguanides are considered Primary Disinfectants
3. Slow dissolving Chlorine tablets (trichloro) can dramatically Lower pH; Quick dissolving Dichlor is relatively pH neutral; Cal-Hypo can dramatically Raise pH.
4. Halogens tend to dramatically dry out skin & hair.  Optimizer Plus® adds borates to the water which significantly aids in softening the water thereby lessening the drying effects.  Optimizer Plus® is a proven additive for ALL pool care systems.
5. ALL Pool Filters should be Chemically cleaned (Strip Kwik or Kleen It for chlorinated, brominated, Pristine Blue®, Nature2® pools OR Soft Swim Filter Cleaner for Soft Swim® or other biguanide treated pools) at least 2 times per season to prevent build-ups of greases, oils & other unfilterables.

1. Trichlor - many cheaper, imported foreign brands of trichlor use gummy binders to hold the trichlor in its shape.  All BioGuard® brand Tablets & Sticks DO NOT USE binders.  BioLab's patented high-pressure process keeps these products together longer.  BioGuard® tablets & sticks dissolve more evenly (don't crumble) for days longer than almost all other brands.  BioGuard® Smart Sticks® manufactured with patented SmartGuard® last even longer & are made specifically for wall skimmer application, no chlorinator needed!
2. Trichlor blends are patented under the BioGuard® Everyday Chlorinating Granules (ECG). BioGuard® Everyday Chlorinating Granules do not cloud the water, are completely soluble & may added directly to the pool or into the pool skimmer.
3. Cal Hypo - available as granules or tablets.  Most of the product is used a granule.  Ideally should be pre-dissolved prior to introduction to the pool water.
4. Percentage of available chlorine for Dichlor varies depending on the product; Anhydrous - 62% or Dihydrate - 56%.
5. Daily Dosage - ounces of product per 10,000 gallons per day at 75° F water temperature to maintain a level of 1.0 - 3.0 ppm Free Available Chlorine (FAC). Please note that consumption will approximately double for every 10° rise in temperature.
6. Fluid ounces. 

*Follow the instructions given by your pool care specialist EXPLICITLY. Failure to do so could result in harm to you and/or your pool & its components.
