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.
Here are a few common issues, causes and solutions:
- o High pH – use pH Decreaser to lower to 7.2-7.6 ppm
- o Dirty Filter – check filter system, backwash if needed. Use a Filter Cleaner regularly and use a Clarifier to improve filtration efficiency.
- o Low Chlorine – shock pool and/or add chlorine to raise free chlorine level to 1-3ppm
- o High Alkalinity – use Alkalinity Decreaser to reduce to 80-150 ppm
- o Hazy water (green algae) - shock pool then use an algaecide for removal and continual prevention
- o 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:
- o Dissolved iron or manganese in water – use a rust and scale remover as directed, run filter until water is clear
Eye and Skin Irritation:
- o Chlorine levels too high – shock pool, run overnight, use a chlorine reducer if needed.
- o pH level too high or too low – use pH Decreasers and Increasers to adjust to 7.2-7.6 ppm range
- o Chlorine level too high – shock pool, run overnight, use a chlorine reducer if needed.
Calcium Scale Build-Up:
- o pH too high – use pH Decreaser to lower to 7.2-7.6ppm
- o Alkalinity too high – use Alkalinity Decreaser to reduce to 80-150 ppm
- o Calcium content too high – use a rust and scale remover as directed
Corrosion of metal parts:
- o pH too low – use pH Increasers to adjust to 7.2-7.6 ppm range
- o Alkalinity too low – use Alkalinity Increaser to raise to 80-150 ppm
Eating through chlorine too fast:
- o Stabilizer is gone – ensure you use stabilizer and stabilized tablets if possible
Ugly “ring” at waterline:
- o Grease and oil from swimmers – clean walls and surfaces regularly using a surface and tile cleaner
