FROG Sanitizing Minerals last 6 months, or one pool season, whichever is shorter, then they need to be replaced.
Once the FROG Sanitizing Minerals are wetted, or after six months, whichever happens first, they are no longer viable. They must be replaced to get the benefit. Otherwise, it’s an empty cartridge – it may sound full and feel full, but the minerals inside are spent.
If you don’t replace your Mineral Reservoir, you’re simply putting too much chlorine in your pool, or worse, not putting enough in to effectively kill bacteria.
It’s part of pool opening to put a fresh Mineral Reservoir in your Pool FROG system every season.
And replacing it is a snap – watch how to do it here:
