Smartchlor is the easiest way to take care of your spa's water. The new, EPA-approved chemical automatically releases chlorine as it is needed. As a result, you end up using up to 75% less chlorine in your spa!
This is a three pack of Smartchlor cartridges for use with the floating system. We don't recommend using it without the floating mineral cartridge as it will drastically reduce the effectiveness and lifespan of the cartridges. We can't even guarantee that it will properly float without using it, actually!
