Spa water turns cloudy because it fills with millions of suspended particles so small they pass straight through your filter. Individually, they're invisible — but together they scatter light and give the water its dull, hazy look. Sirona Spa Clarifier is a coagulating agent: it neutralizes the tiny electrical charges that keep those particles apart and repelling one another, allowing them to bind together into larger clumps.

Once those clumps grow big enough, your filter can finally catch them as the water circulates — physically removing the haze rather than just masking it. That's why clarity keeps improving over the hours after you add it: the particles are steadily being gathered up and filtered out. And because it works mechanically on particles rather than chemically on your water balance, it won't throw off your pH or sanitizer.

Pro Tip: A clean filter is what finishes the job. The clarifier's whole strategy is to make particles big enough for your filter to trap — so if your cartridge is dirty or clogged, it can't hold what the clarifier delivers. Rinse your filter before you treat, run the circulation afterward, and rinse again a day later to flush out everything it captured.

Add directly to the spa water with the blower and jets running, then allow the water to circulate. Dose by your spa's volume, using 1 fl oz per 250 gallons (or 2 fl oz per 500 gallons).

Start-Up

1. When the spa is initially filled or returned to normal operation, add 1 fl oz per 250 gallons of spa water.
2. Pour it directly into the water with the blower and jets running.
3. Allow the jets and blower to run for about 15 minutes, then let the spa circulate and filter.

Weekly Maintenance

1. Once a week — or any time the water looks dull or hazy — add 1 fl oz per 250 gallons (2 fl oz per 500 gallons).
2. Run the jets and blower for about 15 minutes, then allow normal circulation. Many users see noticeably clearer water within hours.

Pro Tip: More is not better with clarifier. Follow the dose — overusing it can actually cause temporary cloudiness of its own, because too much coagulant leaves fine clumps the filter can't quite grab. If a single dose hasn't fully cleared the water, give it a full day of circulation and clean your filter before adding any more.

Sirona Spa Clarifier is compatible with all sanitizer systems — bromine, chlorine, salt water, ozone, minerals, and biguanide. Because it works on suspended particles rather than your water chemistry, it slots into any routine without changing how you sanitize or balance.

It's part of the broader Sirona Spa Care line of sanitizers, balancers, and specialty products designed to work together for safe, restorative, beautifully clear water. It pairs naturally with your pH and alkalinity balancers, an enzyme or phosphate remover (which tackle the dissolved oils and phosphates a clarifier doesn't), and Sirona test strips to keep the whole picture in range. Add it directly to the spa water; never mix it with other products in the same container.
