FROG Maintain for Hot Tubs - Non-Chlorine Shock for use with All Hot Tub FROG Sanitizing Systems - Single Dose Packets for Easy Hot Tub Maintenance & Treatment - 12 Pack

FROG Maintain Non-Chlorine Shock for Hot Tubs is one of my favorite products. This was my 6th purchase and I will continue to purchase it as needed. This product works with the Frog Serene Bromide Cartridge system which I have used for the past 5 years. It may cost a bit more than other systems but it is well worth the price to never have to fight and fuss with the costant measuring and testing of other brands. I use this "maintain" product about once a week along with the cartridges . There is no chlorine smell and never any chance of burning or stinging. It keeps our hot tub water crystal clear. No muss no fuss! It makes hot tub ownership a luxury rather than a chore.

First spa product that is easy to use to maintain my spa. Price is good and keeps my spa water clear and smelling good.

This is a great maintenance product and keeps my spa perfect week after week!

Love this stuff, so easy to use. Non chlorine no smell and works perfect for the hot tub.

I bought a knock off and it ruined my water. They are awesome.

I love these things. It's like a nice little pick me up for your spa. Just like with other frog products... They should be cheaper. If there was a generic alternative for less I'd buy them. But from what I can tell they work as intended

Mt brother-in-law told me about the FROG products for hot tubs. Easiest maintenance ever

Great price!!!
