How fast does it work?

Foam typically collapses within 60 seconds of dosing.

Does it affect chlorine or bromine?

No. The silicone emulsion has no chemical interaction with chlorine, bromine or pH.

Can I bathe straight after dosing?

Wait 30 minutes for the antifoam to disperse fully through the water.

How many doses does 1 L cover?

Around 25 standard doses for a 1500 L hot tub.

Is it safe for inflatable hot tubs?

Yes. The product is safe for vinyl, acrylic and inflatable surfaces.

Will it work in a pool?

Yes. Use 25 ml per 1000 L for pool foam knockdown.

What is the active ingredient?

Polydimethylsiloxane (PDMS), the standard food-grade antifoam used worldwide.

Does it raise total dissolved solids?

Marginally. Long-term reliance on antifoam can creep TDS toward 1500 ppm; refresh part of the water if doses become weekly.

Why is calcium hardness related to foam?

Calcium binds the surfactant-like body oils that would otherwise produce foam. Soft water has nothing to bind the oils, so foam forms easily.

Foam keeps coming back?

Test calcium hardness; raise to 150-200 ppm with Calcium Hardness Increaser.

Cloudy water after dosing?

Reduce dose to 15 ml per 1000 L next time and run filter for 24 hours.

Sanitiser dropping after dosing?

Shock with MPS at 17 g per 1000 L; check filter is clean.

Foam Away vs household antifoam?

Household antifoams often contain solvents that attack acrylic. Foam Away is hot tub safe and pH-neutral.

Foam Away vs sparkle clarifier?

Foam Away knocks foam down in seconds. Clarifier groups fine particles for filtering and is not a foam fix.
