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.

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.

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!

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!!!
