3-in-1 Weekly Hot Tub Chemicals & Spa Chemicals - Cleaner Clarifier Conditioner for Inflatable & Acrylic Spas - Chlorine Bromine Saltwater - No Draining, Made in USA, 32oz Bottle (16 Week)

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.

Bio Ouster works great and keeps our hot tub clean and sparkling.

I've been using this once a week treatmenfor about a year now and this is an easy method to keep your hot tub water crystal clear and safe

Super easy to use and left hot tub clean

Great product

I thought product would help eliminate the Merkis in the hot tub water. It did not.

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.

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!!!
