Bio Ouster 3in1 ウィークリーコールドプランジ水処理 - コールドプランジクリーナー、クラリファイヤー、柔軟剤 - コールドプランジ用ウォータースタビライザー アイスバスクリーナー コールドプランジアクセサリー (32オンス)

Easy and simple to use, straight forward instructions and dosing, great value as once initial dose is done periodically topping up required, good size last and water clarity and smell is great

Delivered as promised. Works great in my cold plunge. Highly recommend. Just set cold plunge for the season. Add the bio ouster, water was crystal clear within about an hour

I spent 40 euro on this thinking it would keep my cold plunge clean and safe. At first the water looked clear but after three days I started to notice itching on my skin every time I got out. That is when I learned this product is only a clarifier and softener. It does not sanitize the water. The label says you still need to buy a separate sanitizer such as chlorine or bromine. So on top of the 40 euro already spent I now have to spend more money elsewhere to make the plunge usable. It might help with water clarity but it is not a full solution and it gave me skin irritation after a short time. If you want a safe cold plunge you will need to add a real sanitizer.

Super easy to use. There is no odor. I think its very important to use to keep your chiller clean.

awesome product I cannot believe how much longer my water lasted by adding this product. Everything was crystal clear for months. I will definitely buy again when I'm out of this product. Should last me a long time.
