Orb-3 Y240-000-1Q Spa Enzymes Bottle, 1-Quart

I used this for awhile but I ended up having a lot left over when it said it expired. I did notice a lot more foam in the tub when using this. It works ok but you have to use the defoaming stuff to control it and you have to keep on adding get it the foam stuff cause it just subsides it. I haven't bought it since.

This product keeps my Intex hot tub crystal clean, started using it now in my stock tank.

Removes bromide smell

While I still use some of the other chemicals, this stuff seems to be what works best... and i use less of the other stuff. Really cleans up the tub. Yes, after you put it in and let it work, you need to clean up the ring around the top (ok, maybe I need to shower before getting in the tub!), but it leaves the water very clear and clean.

This works great. I had a recurring problem with bacteria that i think was in my pipes. Was persistent and kept coming back. This cleared it out after a couple applications.

First time purchase, appears to be working as described.

Helps keep the spa clear - good value on price

this product really helps to prevent wild swings in the chemical balance as well as helping the water feel silky smooth!

This worked way better than the Beachcomber brand. I no longer have issues with scum. And you don't need as much.

good product
