Product details

This is the Spa Frog 150 gram bromine cartridge, King Technology part 702741. It is the bromine half of the Spa Frog mineral and bromine system, and it works in both the floating holder and the in-line housing.

How the system works

Spa Frog runs a mineral cartridge and a bromine cartridge together. The minerals carry part of the sanitizing load, which means the bromine side does not have to run as hard. The practical result is less bromine in the water and a spa that feels softer to sit in, with less time spent testing and adjusting.

How often to change it

A cartridge lasts two to four weeks. Where you land in that range comes down to the size of the spa, how many people are using it and how often it runs, so a small tub used by two people goes longer than a large one used by a crowd every weekend.

Already fitted on many spas

A number of spa manufacturers install the in-line Spa Frog at the factory, including Emerald, Caldera, Leisure Bay, Marquis, Morgan, Watkins Hot Spot, Pacific Hot Tubs and Saratoga. If your spa is one of those, the housing is already in the plumbing and this cartridge drops straight in.

Questions and answers

What people ask about this product, answered by our pool techs.

How long does one cartridge last?
Two to four weeks. The spread depends on how big the spa is, how many people use it and how often, so a busy family tub lands at the short end.
Do I need the mineral cartridge as well?
That is the point of the system. The mineral cartridge does part of the sanitizing work, which is why the bromine side can run at a lower level and the water feels softer.
Does this fit the floating Spa Frog or the in-line one?
Both. The same cartridge is used in the floating holder and in the in-line housing.
Does my spa already have a Spa Frog fitted?
Several manufacturers install the in-line system at the factory, among them Emerald, Caldera, Leisure Bay, Marquis, Morgan, Watkins Hot Spot, Pacific Hot Tubs and Saratoga. Check the plumbing bay for the in-line housing.
