How long will chlorine last at fully open position?
A shopper on Jul 4, 2018
BEST ANSWER: That, of course, depends upon two factors: the temperature of the water and how long you run your pump each day. In summer, when the water is warm, and if you ran your pump 24/7, you could easily dissolve a full load of 3-inch tablets (9-10 tablets) in a week.
I have a 320 chlroinator that the cap is stuck and the ears on top are broken off. Do you have a suggestion for getting the cap off?
John E on Apr 3, 2017
BEST ANSWER: The easiest solution is a "strap wrench." These consist of a rubber strap connected to a hard plastic handle. You loop the rubber strap around any round object and back through the handle, then apply pressure with the handle and the cap should spin right off. Strap wrenches are available at Home Depot, Lowe's, and other tool/hardware stores for around $20.00.
DO YOU HAVE ANY CHLORINATORS ?
A shopper on Feb 23, 2021
Will this work with my above ground pool with Pentair filter?
Terry S on Aug 11, 2021
BEST ANSWER: I have an in ground pool and the 320 automatic chlorinate works just fine. My neighbor has an above ground pool with a similar filter. I would say yes it should work, but I would consult a local pool store/pool install company. Cheers

Easy
Easy to install and use and much better than the tablet floaters I had in the pool and spa that the kids always seem to flip upside down and the lid would come off and tabs would sink to the floor.
