The New HASA Liquid Feeder Sanitizes Daily Hands Free

What Pool Pros are Saying:

“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.”
