FROG Replacement Mineral Reservoir for In-ground Pools

Replace the FROG Mineral Reservoir for In-ground Pools in your FROG In-ground Chemical System at the beginning of every season. The mineral reservoir is what helps sanitize the water at the low dosage of sanitizer. Replacing once a season allows your pool to be stress free, healthy, and reduces chemical use. Simply recycle the old cartridge and slide in the replacement. Always be sure to activate the mineral pack with a chlorine based shock oxidizer.
