Pool Chemical Buying Guide

 

Are you overwhelmed by the number of chemical varieties for your pool? You are not alone. This guide should help you narrow down your choices.

 

First thing to go over are the different types of chemicals:


Algaecides are intended to be used to treat and prevent algae growth. Algaecides may be for a specific type of algae, some may be a generalized algaecide.

Clarifiers are intended to remove the particles that can often cloud your pool by coagulating them making it easier for the filter to do its job.

Balancing Chemicals feature a variety of chemicals to maintain and adjust your water to the perfect chemistry. They include Chlorine or Bromine, Alkalinity Decreasers and Increasers, Hardness Increasers, pH Decreasers and Increasers, and Stabilizers/Conditioners.

Flocculants
cause the particles causing cloudiness to fall to the bottom of the pool for easy vacuum removal.

Filter Cleaners and Enhancers are used to make cleaning your pool filter easier and more efficient.

Natural Chemicals
use a mineral system to be an alternative to chlorine.

Stain and Scale Controls are used to remove stubborn stains caused by metals built up in the pool.

 

Chemical Accessories include tablet feeders, ozonatorssalt systems and water test kits.

 

Here are a few common issues, causes and solutions:


Cloudy Water:

  • High pH – use pH Decreaser to lower to 7.2-7.6 ppm
  • Dirty Filter – check filter system, backwash if needed. Use a Filter Cleaner regularly and use a Clarifier to improve filtration efficiency.
  • Low Chlorine – shock pool and/or add chlorine to raise free chlorine level to 1-3ppm
  • High Alkalinity – use Alkalinity Decreaser to reduce to 80-150 ppm


Green Water:

  • Hazy water (green algae) - shock pool then use an algaecide for removal and continual prevention
  • Clear with green tint (copper in fill water) –use a rust and scale remover as directed, wait overnight, test and adjust chlorine and pH levels


Reddish Brown Water:

  • Dissolved iron or manganese in water – use a rust and scale remover as directed, run filter until water is clear


Eye and Skin Irritation:

  • Chlorine levels too high – shock pool, run overnight, use a chlorine reducer if needed.
  • pH level too high or too low – use pH Decreasers and Increasers to adjust to 7.2-7.6 ppm range


Chlorine Odor:

  • Chlorine level too high – shock pool, run overnight, use a chlorine reducer if needed.


Calcium Scale Build-Up:

  • pH too high – use pH Decreaser to lower to 7.2-7.6ppm
  • Alkalinity too high – use Alkalinity Decreaser to reduce to 80-150 ppm
  • Calcium content too high – use a rust and scale remover as directed


Corrosion of metal parts:

  • pH too low – use pH Increasers to adjust to 7.2-7.6 ppm range
  • Alkalinity too low – use Alkalinity Increaser to raise to 80-150 ppm


Eating through chlorine too fast:

  • Stabilizer is gone – ensure you use stabilizer and stabilized tablets if possible


Ugly “ring” at waterline:

  • Grease and oil from swimmers – clean walls and surfaces regularly using a surface and tile cleaner
