Multi-Chlor

Hi, guys. I'm Brian with Hasa. Today, we're gonna be looking at Hasa's Multichlor, a twelve and a half percent sodium hypochlorite solution that's registered for a wide range of applications, including shocking and sanitizing swimming pools and spas. Multichloro is NSF sixty certified for drinking water.

It goes beyond your pool with uses in sewage and wastewater, public water systems, medical and laundry sanitization, and many other water based systems. Just ten fluid ounces of multi chlor will increase the chlorine level of a ten thousand gallon pool by one part per million. For a new pool startup or spring startup, super chlorinate with fifty to a hundred fluid ounces of Multichlor for each ten thousand gallons of water. It'll yield five to ten parts per million available chlorine by weight.

Don't exceed levels of four parts per million.

To maintain the pool, add manually or buy a feeder device eleven fluid ounces of this product for each ten thousand gallons of water to yield an available chlorine residual between point six and one point zero parts per million by weight. Test the pH, available chlorine residual, and alkaline in the water frequently with a reliable test kit. Frequency of water treatment will depend upon temperature and the number of swimmers. Hey. This is Brian with Hasa. Thanks for checking in, and we hope this short video was helpful. For more information, please visit us at w w w dot hasa pool dot com.
