Sparkle Clarifier (Spa)

Restore brilliant sparkle to dull hot tub water. A polymer-based clarifier that gathers fine particles too small for the filter into clumps it can catch in a single pass.

• Clears dull or hazy water in 4-12 hours.
• Groups fine particles for capture by standard cartridge or sand filters.
• Boosts apparent water sparkle without affecting sanitiser.
• Safe with chlorine, bromine, MPS and salt-water systems.
• Improves filter efficiency for the rest of the cycle.

When you need it

• Water has gone dull or slightly hazy without a clear reason.
• Filter is clean but particles still pass through.
• It is the day before guests arrive.
• You have just shocked and want to restore clarity faster.
• A fresh fill is taking longer than expected to clear.

How to use

1. Test sanitiser, pH and alkalinity; ensure all are in band first.
2. Switch the pump to circulation mode (not full jets).
3. Pour 50 ml of Sparkle Clarifier per 1500 L into the skimmer.
4. Run circulation continuously for 4-12 hours.
5. Check filter pressure; rinse the cartridge or backwash if pressure has risen 25 kPa.
6. Retest sanitiser and pH; rebalance if needed.

Dosing guide

One dose is enough for most haze events. If water has not cleared in 12 hours, check pH and sanitiser before redosing.

• For 1,000 L, add 35 ml to reach Standard polish.
• For 1,500 L, add 50 ml to reach Standard polish.
• For 2,000 L, add 65 ml to reach Standard polish.
• For 5,000 L (swim spa), add 165 ml to reach Standard polish.
• For 10,000 L (pool), add 330 ml to reach Standard polish.

How it works

A water-dispersible polymeric clarifier based on cationic flocculants designed to bridge between fine suspended particles in pool and spa water.

Cationic polymer chains attach to negatively charged fine particles (skin cells, algae fragments, lotion droplets) and bridge them together into larger clumps. These clumps are then captured by the filter on the next pass, leaving the water polished.

Standard cartridge and sand filters cannot catch particles below 5 microns. Without a clarifier, fine particulates accumulate, scatter light and dull the water. A single dose lifts apparent clarity dramatically and reduces the load on the sanitiser.

Frequently asked questions

How long does it take to work?

Most water clears within 4-12 hours of continuous circulation.

Does it affect sanitiser?

No. The polymer is inert to chlorine, bromine and MPS.

How often should I use it?

After every water change, every shock and any time water looks dull.

How many doses does 1 L cover?

Around 20 doses for a 1500 L hot tub.

Is it salt-water safe?

Yes. The clarifier is safe for salt chlorinator cells and salt-system spas.

Will it remove algae?

It will help remove dead algae fragments after a shock; live algae must be killed by sanitiser first.

What is the active ingredient?

A high-charge cationic polyelectrolyte (poly-DADMAC family).

Why does pH matter for the clarifier?

At pH above 7.8, the negative charges on suspended particles are weaker, so the polymer cannot bridge them effectively.

Does it raise total dissolved solids?

Marginally. 100 ml per 1000 L adds about 50 ppm TDS.

Water still cloudy?

Check pH is 7.2-7.6, alkalinity 80-120 ppm; redose after rebalancing.

Filter blocked after dosing?

Expected. Rinse the cartridge or backwash; the polymer has captured the haze.

Greasy film on the surface?

High body-oil content. Clean cartridge overnight and dose Foam Away.

Clarifier vs flocculant?

Clarifier groups particles for the filter; flocculant settles particles to the floor for vacuuming. ClearSpa Sparkle is a clarifier.

Clarifier vs Foam Away?

Clarifier polishes hazy water; Foam Away knocks foam down. They solve different problems and can be dosed together.
