Can I use PristineBlue if my spa has an ozonator?
Absolutely! In fact, PristineBlue is a great complement to ozone sanitisers. Ozone has a quick kill (and is only working when the fitration pump is running) but has a very short residual effect, allowing bacteria and algae to re-grow. PristineBlues extremely long residual effect prevents algae and bacteria from returning to your water.
