    • Happy with these cartridges
Size: 3 Pack
My Marquis Resort fills with 360 gallons. These sanitizer cartridges last for 3 weeks on a setting of 3. I haven’t tried a setting of 2, to see if it lasts longer. I’m very satisfied with this feature and how it functions.

    • Works as advertised. I wish they lasted longer
Size: 3 Pack
Chlorine is chlorine is chlorine. Whether it's in a tablet, a bucket, or wherever. My only complaint is that the cartridges only last about 2-3 weeks, depending on our usage, which is every single day. So I suppose if we only used it once in a while they would last longer, but why would you spend $15k on a hot tub and not use it every day? I MEAN, COME ON! ... show more
