Thought I would throw this out to the Seebreeze knowledge base.

Does any one know of the best way (easiest way) of removing calcium build up from a spa?

I have read that you can use white vinegar, or baking soda?

Has any one any experience with resolving this issue?

Thanks in advance

flame thrower ?

Are you sure it's calcium?

Sorry no idea.

But if you're interested I run an ozone generator to purify my water and have done for years, water's always crystal clear no chemicals. I don't know what causes calcium build up, never had it so take that how you want but Google ozone and spas and see what you think, might help down the road ?

I did it for you. You're welcome.

Firiebob, thx will look in to that.
Dan, thanks but really.... I can google I asked "Does any one know of the best way" & "Has any one any experience with resolving this issue?"

Ok, just don't bother clicking on the 8th result or you will end up back where you started...

Now number 7

Avoid milk cheese and yogurt in the spa
