Great product if you don't like smelling chlorine and breathing in vapors. This is easy to replace. Note: make sure your stabilizer is adequate or this cartridge will be used up quickly. A Frog mineral pool uses .05 chlorine which is healthier for swimmers. Keep water balanced, shock weekly, because with such low chlorine levels it can go down hill real quick with a heavy bather load, high temps, or high rain levels. Don't be lazy, pick a day to test, add chemicals (usually alkanity is all we need), throw in shock and pool holds nicely for over a week. Easy Peasy!!
