Nothing Better
I’ve been using Bio Ouster 3 in1 Weekly Hot Tub Cleaner, Conditioner, Clarifier for about 6 weeks now. I promise my Hot Tub is cleaner and clearer than ever. Even my filter looks good. No more guessing with PH balance, water clarifier, ect.Notes: use weekly as directed, continue to use Bromine tables. After using Bio Ouster, you very likely will have to wipe down the sides and use a pool net to remove the scum buildup from the foam, which is an easy clean. I use a little deformer to help concentrate the cleaning process. Works quick, cleaning time takes about 10 minutes. No bad smells, great product, worth every penny of my money.

Keeps My Hot Tub Crystal Clear!
This 3-in-1 hot tub cleaner kit has made my spa maintenance so much easier. I just add it once a week, and it handles everything—cleans, conditions, and clarifies. The water stays sparkling clear, feels softer on the skin, and I don’t have to mess with a bunch of separate chemicals.The packets are pre-measured, which takes the guesswork out of dosing, and it works great in both my inflatable spa and a friend’s standard hot tub. I’ve noticed way less cloudy water and buildup since I started using it. Plus, I love that it’s made in the USA.

works as advertised. Been using this product for 4 months, water is always clear. I range 7 to 10 days between treatment, depending on use. Great product.

Start with clean water and you will be fine!
Works great, keeps the water clean, soft and clear. I believe negative reviews are from people trying to clear up already dirty water. Have some common sense, drain, clean, fill with with clean water, add this and it will stay clear. When it gets cloudy in a few weeks, add another. I’m using for a Coleman inflatable hot tub.

I bought these because I liked the idea of the pre measured packets. Unfortunately I don’t notice a difference in the clarity of my water at all when I use them. I have an actual bottle of clarifier and it is much more efficient. Probably wouldn’t buy again.

Ok when proceed in$30s but over that is crazy.

The product did balance the chemical levels, but it made the water murky after a day or two. I had to add in clarifier and it took 3 days to get it back to clear water. I’ll just stick to my basket of pool chemicals and balance them myself….
