What Pool Pros Are Saying about the Liquidator Daily Feeder

“The easy to install liquid feeder system from HASA Pool is inexpensive and compact. It’s a great way to feed chlorine into your pool minus the side effects of 3″ tabs. It reduces the drop in pH that that comes along with tab feeders, making chemical balancing easier for even the most novice customer.”

Did you know?

As the de facto standard for liquid sanitization, HASA products including Hasachlor®, Multi-Chlor® and Sani-Clor® have set the bar for reliability and sustainability since our inception. Sodium hypochlorite is made from naturally derived products. After it cleans industrial and commercial water systems and recreational water sources (such as private and commercial swimming pools, spas and hot tubs), it returns to salt—and is safe for our oceans and communities.
