Flippin' Frog Replacement Chlorine Cartridge

For pools, add a stabilizer or conditioner if the level is below 20 ppm. Follow the manufacturer’s directions. Algaecides are also helpful.

For spas, clarifiers can be helpful for occasional cloudy water.

Ionizers due to the duplication of minerals and biguinides like Baquacil that are not compatible with chlorine or bromine.

Total chlorine is the total amount of chlorine in the water. When chlorine binds up with contaminants it forms a compound called “chloramines” 

that are still part of the total but no longer effective. The chlorine that is still active to remove contaminants is known as free. When the 

chloramine level is higher than the free chlorine level (subtract free number from total), then you need to shock the water.

Silver and limestone. The silver destroys bacteria and the limestone absorbs acids from chemicals like chlorine to help maintain a neutral pH.

For pools, FROG minerals last six months or one pool season whichever is shorter. Once removed from the water, the minerals may not be reused the 

following season. For spas, FROG minerals last 4 months. Simply replace every four months or whenever you drain and fill your spa.

Water supplies contain different levels of natural minerals like iron, copper or magnesium. These minerals must be removed from the water with a 

Metal Out or Sequestering Agent (see your dealer) to ensure easier balancing and proper sanitation. If using our FROG Mineral products, make sure 

you remove the natural water minerals at start up only and wait 24 hours to clean the filter before using the FROG minerals.
