Pool Frog 5100, 6100 Mineral Reservoir Cartridges

Pool Frog 5100 and 6100 Replacement Mineral Reservoir Cartridges for Above Ground Pools

Pool FROG for above ground swimming pools up to 25,000 gallons. FROG Mineral Reservoirs for above ground pools contain a natural, yet proprietary blend of minerals that destroys bacteria, algae and helps to maintain your pool pH water balance.
Frog mineral cartridges fit inside the Pool Frog Cycler feeder. The Pool Frog minerals continually replenish themselves for added protection against bacteria and algae, as well as keeping your pool's pH balanced by acting as a neutralizer. 
The mineral cartridge will last a full swim 6-month season for most swimming pools; use two reservoirs for year-round swimming pools.
Pool FROG mineral cartridges will also work with the original New Water 100 Series Cycler feeder. This offers the opportunity for New Water chlorine feeder owners to upgrade to better water clarity and softness with less chlorine. Note: only your dial settings will be slightly different using thePOOL FROG Mineral Reservoir cartridge in place of the NEW WATER 105C Chlorine Pacs.
