Mineral Cartridge, Spa Frog® @Ease® In-Line System
Sku: 78418-1
$47.54
@Ease® mineral cartridge for Spa Frog® for Hot Spot models beginning in 2019.
How long do the Mineral and SmartChlor® cartridges last? The mineral cartridge lasts four months or whenever the hot tub is drained and refilled. The SmartChlor® Cartridge lasts 3-4 weeks depending on the size of your tub and how often it is used.
The @ease® System combines the proven FROG® mineral formula for killing bacteria with SmartChlor® Technology that maintains a consistently low chlorine level for weeks.
Unlike normal chlorine that is used up when you get in, SmartChlor® continues to maintain the same level which is up to 75% less than hot tubs using Dichlor (standard hot tub chlorine). That’s why we call it self-regulating. It goes to work when the hot tub needs sanitizing so there are no frustrating yo-yo chlorine levels. This time-released method is also why less shock is needed to maintain the hot tub. When the SmartChlor® Cartridge is depleted, the FROG® @ease® Test Strip will show a lighter color than the out indicator on the bottle.

The videos were great at guiding me to the problem with my hot tub. A few entries as to the make and model of my hot tub, and there was the part I needed. A few more entries and my replacement part was on its way. They even had a video with a helpful trick to purge the air from the system once installation and filling was complete. I'll keep this website in my favorites but hope I won't need to use it soon. Perfect for the do-it-yourself fat old bald guy!

Hi there-
I see that you ordered a filter lid which is a special order item. The factory makes these to order and it can take anywhere from 2-4 weeks for them to make the item. I see you placed your order 2 days ago and also selected the free shipping at checkout. Once this item comes in, we will ship it out same day and we will ship via Fed Ex Home Delivery. Please feel free to reach out to us customer_care@backyardplus.com if this is still unacceptable and you wish to cancel your order.
Thanks,
Rebekah
