What’s Your Pool Care Routine

“I Use a Pool Service Pro”

Using an outside pool professional is a great choice! Relax, enjoy your pool, and rely on the support of a qualified technician. Most pool pros prefer the quality, freshness and high performance of our Sani-Clor® liquid sanitizer. They know that liquid product doesn’t add CYA or calcium—allowing the chlorine in your pool to work most efficiently to cleanse and disinfect your water. Plus, only liquid pool chlorine from HASA (at 12% concentration) can generate the most beautiful, sparking blue pools!

A Better Acid Wash

Try adding HASA Super Stain-Out® to your acid washes. Super Stain-Out® will help the stain to release from the plaster. Just add 4 oz. of Super Stain-Out® to your acid wash solution. This Super Stain-Out® acid wash solution will amaze you with how quickly it will pull the copper stains out of white plaster. This solution will leave the plaster white after just one application. It's gentler on the plaster, and it's less labor and cost to you.

 

Seasonal Tips

Tip 1: Manage the Summer Heat

Evaporation from extreme summer heat can tinker with your water levels. Take care to monitor pool water consistently for greater chlorine performance—and safer swimming for guests and all members of the family—during the peak periods of hot summer weather!

Tip 2: Make Sanitizing Easy

Want to streamline the daily dispensing of liquid chlorine 365 days a year? The HASA Liquid Feeder™  automatically feeds liquid sanitizer into your pool year-round, regardless of the season, for greater hassle-free ease of use and better cost savings.

Tip 3: Year-round Pool Care

At the end of pool season, make sure to check and balance pH and alkalinity levels—along with overall chlorine count—to make pool care and maintenance easier in the “off-months.” This helps to ensure a gorgeous blue pool once warm weather kicks back in.
