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.

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.
