Spa Ag+ Mineral Sticks for Hot Tub, Silver Ion Mineral Cartridge Last for 4 Months Treats (4PCS, Grey)

Got these for our hot tub. Great product at a great price. Half the price of same product at a spa place

Helps reduce the amount of chemicals needed in the hot tub. It fits into the "floater" so use it instead of adding bromine tabs. The hot tub is cleaned often but it helps to keep the water clean in between and its effectiveness seems to last approximately 3 months. For some reason it is not available in Canada.

If you want a cheaper version of a silver ion sanitizer cartridge for your hot tub, this product is ideal because it is roughly half the price of cartridges from more traditional suppliers. It seems to work just fine so rates two thumbs up!

Nine month update. Water is perfect, these work as good as HS's for a whole lot less. 5 starsFour month update. Water is perfect, so far I see no difference. Will use 1 more and change raiting to 5.I didn't think it was going to fit so I kind of man handled it and the top came off, outcame the contents. So the man in me went to the Wakens old one and took the top off it. First of all it was a chore to get it off versus the Billinavy. So what's inside? Let me first say I will test this before I say anything bad about it but I already blew $12:00 so lets see. Like most of you I assume gave this a try because it had the exact formula and looked the same. We dreamed maybe we found the wholesaler or something like that. If it works the same I will be the first to say in 4 months. So what did I find? The housing looks the same but it has lighter walls. It's thinner (making it easer to open) It's just lighter all around. 2nd I what I think is the important part is the silver. The Wakens bottom 25% is what I think is silver of some kind. The Billinavy has smaller chunks thru out a lot les but who knows it may me stronger. Proof will be in the water over the next few months. But I for now I'm sure that are not the same. I gave it a 4 and hope to change it to a 5. and not a 1. Stay tuned.

Great value

So easy to use...

Great item, fast turnaround.

Was tired of buying some of the spa product from store at such a high cost. I've finally found some good replacement products that are a good value and i dont cringe when i have to purchase them.Ratings - product is a no brainer to install and so easy so why not give those a high rating. The value proposition was the deciding factor.
