SpaSILVER™ Water Booster Preserves Hot Tub and Spa Water - Concentrated True Colloidal Silver - 500 mL in Blue Plastic Bottle

My friend uses colloidal silver in her hot tub but she makes it herself. Not me. So I ordered this and it is great!

I've got a sinus infection back in April. After 3 rounds of antibiotics, 5 doctor office visits, threats of surgery, and several home remedies like essential oils, I was still sick in November! I read an article that said that using Colloidal Silver regularly can stop chronic sinitus, so I decided to try it. I bought this colloidal silver and some empty nasal spray bottles and gave it a try. About 2 weeks later, my sinuses were clear for the first time. About 4 weeks later, I no longer had stuffy ears, or runny nose, or any other symptoms. Now I use it once a day just to maintain and prevent reinfection. It's the best $35 I've ever spent. Oh, and I also put a cap full in my home humidifier once a week and I haven't had to scrub it since either. Prior, I had to scrub it with bleach at least once a week to prevent slime from building up inside. Now, I just rinse it out once a week and add another cap of colloidal silver and away we go.

Just got a new spa and someone recommended I try this to rid the spa of the chlorine smell. It did it's job and then some. Love that I can soak in my spa and not smell like I just took a chlorine bath.

Works to lessen need for chlorine. I still need to shock.

great product, eliminates chlorine in our spa. better for all spa users than chlorine and shock.

Works great in our hot tub!!

I have bought spa silver for a couple years for my hot tub and have had no problems. I decided to buy the larger bottle to save a few dollars and it arrived open and used with the 500 mL blacked out. I don't even know what's in the bottle! I think they should replace it free of charge but that's my opinion of course. A refund is no good if you have to throw the product away when you were counting on using it.

Do I need to shock it with this product do I need to use chlorine at all? And how often do I drain it if I don't use a chlorine-based product along with it
