Title: Dirty Ozonator on HS Spa???
Post by: Neohcouple on June 26, 2005, 08:58:31 pm

Greetings:

I am the recent owner of a 2005 Hot Springs Vanguard Spa.  I have had it for about 1 month now (I will be posting a review shortly now that I have been able to enjoy it for a little while).  

Anyways, I have been following the protocol for shocking the tub every week, adding chloring every 1-2 days, etc, etc.  Everything appears to be in balance such as PH, ALK, chlorine, etc.  

However, I am noticing that on the HS Freshwater Ozonator (where the bubbles come up on the spa floor), it appears to be turning a slight brownish color.  Is this normal?  Can I clean this (if so, how)??  Since it is located on the spa floor & is always submerged in water, what is the best way to do handle this?  Hope this makes sense.

Any feedback is greatly appreciated.

To answer your last question first, no this is not normal.
Ozone, like any oxidizer can sometimes oxidize metals out of solution and can cause staining. I would have your water checked soon by someone who can test for metals. One way to see if it is a metal is to take the grate off of the floor drain, since this is what I assume is changing color, and wash it with a very light acid solution or viniger. If the stain comes right off, then you probably have Iron or some other metal in the water. I would recommend using a product called MetalGon, and then maintain weekly with a stain and scale control. Hope this helps. Let us know what happens.

Yup, perfectly normal. It's the iron in the water being oxidized. That's what ozone does.

Try "stain and scale care" from the Freshwater line - available at your HS dealer.

Well, I guess in view of Chas' statement, it could be normal but should not be if water is properly maintained with a stain and scale agent.

I would agree. I see it in most all tubs with the FW III ozone system - less if they have been treated for metal, more if they have not been.

You can clean it off when you do a water change.

Hi Chas:

Thanks for the info.  At least I know the ozonator is working properly.  Right now, I am adding about 1 ounce of "scale & stain" every week when I shock it.  Maybe I should be adding more???

Also, is it possible to clean the ozonator grate before changing the water at my recommended 3 month interval??  The water looks absolutely beautiful, but ozonator grate cover doesn't look so pretty.
