1. Nature2
® or Spa Frog® Spa Care using our recommended systems including PoolBoss® Excel or Chlorine Granules & Soft Touch
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 using PoolBoss® Filter Free 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.
