piece of junk
Do not buy this product.  I have a different brand that I have been using for 5 years and still works great. Bought this for a nephew than he decided he didn't want it and it sat in the sat in the box for a couple months so I thought, well I will use the new one.  Used it to ozonate about 4 gallons of water than it quit work working.  Looked at the instructions and nothing worked. It is a piece of junk.
