works wonders for hot tub
Brings all the gunky stuff to the top for easy cleaning. Never knew that there was so much stuff not filtered out. Makes water crystal clear.

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.

Works Great
This works great for cleaning hot tubs. I use this product at least three times a year. Easy to use and keeps my hot tubs in tip top shape.

Hot tub cleaner
Great for hot tubs. Especially effective if you or other hot tub users use lotions, body oils. Prevents accumulation of lotions, creams, debris in hot tub and keeps water cleaner and clearer longer!

Read directions on amount per gallon
This product is what I expected. Not a strong smell and it works, just read the directions because I used it in my 250 gal portable hot tub and the packet is for 500 gallons.

Product is awesome, bottle sucks
The stuff works great but the bottle/cap leaks on every single bottle I buy and wastes a bunch of product. Please fix the packaging!

Took care of our foam and chemical issues
Has worked very well in keeping our hot tub water clear and chemical levels in check. We were having a problem with soooooo much foam forming and never able to keep the chlorine levels in check. Once we started using this product, everything has been much better - and having to add much less chlorine. Very happy!

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....
