FROGFilter Mate for Hot Tubs - Prefilled Sanitizing Mineral Dispenser Stick - Easy Installation into Filters for Easy Hot Tub Treatment & Water Maintenance

I have been using these for years and it is much easier==and less expensive-- to order on line.

I needed a replacement for the one I had in my hot tub and this was a much better price and fit perfectly! Very happy with the results so far.

Bought this on amazon because I didn't want to go to the spa store. It was cheaper here also. It appears to be the same thing, which is why I am giving it 5 stars. The spa store told us as long as you shake it and there is stuff in it, it's good. Well 7 months later my tub started to smell musty. Read the packaging on this thing and it says even if it has stuff when you shake it, it does not mean it is still good. The sanitizing part of it is gone after 4 months. Got a new one and tub is back to normal. Super easy to use.

Works great, this is about the 6th one we have purchased

Been using this product in our spa for years and along with weekly chlorine and shock I think it plays a significant part in keeping the spa clean and clear!

These seem to work ok, hard to tell. They are much cheaper than the original Frog filter. I have to cut off the end so it will fit in my filter, not a big issue

Love it better than the Ball!

Use this along with the enhanced shock from spaguard! Maintenance of the hot tub is so much easier. I don’t like the frog that floats. It just bangs around and hits the shell of my tub. This thing is perfect inside the filter.
