  • works wonders for hot tub
Size: 8-Weeks (16oz)
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 Nothing Better
Size: 16-Weeks (32oz)
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. ... show more

  • Product is awesome, bottle sucks
Size: 8-Weeks (16oz)
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!

  • Wonderful product
Size: 4-Week Kit (8oz)
I thought I was going to have to drain and refill my hot tub. We got this and thought I’d give it a try to see if it would work to clear up the musty stale old bromine smell. I filled the tub (topped it off with water) cleaned the filter then added a package of this. Within seconds the musty smell was gone and the tub was crystal clear. Glad I bought this stuff and tried it. Should last another month before we need to do a full water change now. In the dead of winter this means a lot!!! ... show more
