Why it works

Why Spas Are Adopting Probiotic Water Treatment

  • Sanitify probiotic treatment eliminates Legionella-supporting biofilm in spa jets, hot tub plumbing, and hydrotherapy circuits
  • Bacillus bacteria digest body oils, cosmetics, and organic residue at spa water temperatures (36–42°C)
  • No chlorine smell in enclosed spa rooms — guests experience genuinely chemical-free hydrotherapy

Dose, Run Jets, Rest

Add the recommended dose to the spa balance tank or directly into the water with jets running. Bacillus bacteria distribute through the entire plumbing circuit within 1 hour, colonising pipe surfaces and digesting accumulated biofilm. Re-dose every 1–2 weeks for hot tubs and 2–3 weeks for larger hydrotherapy pools.

Elegant spa and wellness facility interior — the premium guest experience Sanitify supports

Eliminate Biofilm in Spa Jets and Pipes

Spa jets and hot tub pipes accumulate biofilm rapidly due to high temperatures and body oil input. This biofilm harbours Legionella pneumophila. Standard chlorine only surface-treats this biofilm. Sanitify Bacillus bacteria penetrate and digest the biofilm matrix from inside, eliminating Legionella’s habitat. Independent testing shows >99% biofilm reduction in spa plumbing within 4 weeks of Sanitify treatment.

Chemical odours in enclosed spa rooms contradict the wellness positioning of premium spa facilities. Sanitify eliminates the chloramine formation responsible for this odour. Guests experience genuinely neutral-smelling spa water — a measurable improvement in the premium wellness environment. Hotels and day spas report higher guest satisfaction scores after switching to Sanitify.

Bacillus Technology in Hot Tubs and Hydrotherapy Pools

At spa temperatures (36–42°C), Sanitify Bacillus bacteria are particularly active — warmer water accelerates enzyme production and biofilm digestion. The bacteria are thermotolerant up to 45°C. In hot tub water, Sanitify digests body oils, sunscreens, and organic nitrogen compounds — reducing the substrate that both pathogens and chloramines require.

What customers are saying

Sanitify Probiotic Pool Cleaner has completely changed our pool care. We don’t miss the chemical smells or the irritation – the water is always clean and clear. Best decision we made for our pool!
Liina
We wanted a natural alternative to chlorine for our pool, and Sanitify was the perfect solution. Not only does it keep the pool spotless, but I feel better knowing there are no harmful chemicals around my kids. The water smells fresh, and we couldn’t be happier!
Anne
My kids have sensitive skin, so using chemicals in the pool was always a concern. With Sanitify, there’s no irritation, no red eyes, and the water feels so much softer. I can’t recommend it enough for families!

Frequently asked questions

Is Sanitify safe for use in hot tubs at 40°C?
Yes — Sanitify Bacillus bacteria are thermotolerant up to 45°C. Warmer water increases enzyme activity — hot tubs often see faster biofilm clearance than standard pools.
How do I use Sanitify in a residential hot tub?
Use 10ml per 1,000L. Pour into the skimmer with jets running. Re-dose every 1–2 weeks. After initial treatment, run jets for 30 minutes to flush loosened biofilm from the plumbing.
Will Sanitify eliminate the chlorine smell from our spa room?
Yes — Sanitify reduces chloramine formation, the source of the characteristic spa chemical odour. Spas using Sanitify report complete elimination of the chemical smell within 2–3 treatment cycles.
Can Sanitify help with Legionella risk in our spa?
Yes — Sanitify eliminates the biofilm in which Legionella bacteria colonise. Independent testing shows >99% Legionella reduction in spa systems within 4 weeks. Use as part of a full Legionella risk assessment and management plan.
Does Sanitify work in flotation tanks?
Yes — flotation tanks with high salt concentrations can use Sanitify at a reduced dose (5ml per 1,000L). Effective in saline environments and reduces biofilm in flotation tank plumbing.
How often should I dose a hotel spa pool?
For hotel spa hydrotherapy pools with daily guest use, dose every 2 weeks. For lower-traffic day spa pools, every 2–3 weeks. Hot tubs with high bather loads should be dosed weekly.
Will Sanitify affect the feel of the spa water?
Guests often describe Sanitify-treated spa water as feeling ‘silkier’ than chlorinated water — because it removes the chemical compounds that cause the stinging sensation on skin and in eyes.
Can I continue using existing spa sanitiser alongside Sanitify?
Yes — during transition, maintain existing sanitiser at reduced levels while Sanitify bacteria establish. Most spas reduce sanitiser dosing by 60–80% within 4–6 weeks.
Does the biofilm pipe flush release harmful material?
The loosened biofilm is organic material that is then digested by Bacillus bacteria in the water. Run filtration normally during the flush period. Water may briefly appear slightly cloudy — clears within 24–48 hours.
Is Sanitify suitable for thalassotherapy pools?
Yes — Sanitify is effective in marine and brackish water environments. For thalassotherapy applications, use Sanitify at 1.5× standard dose to account for higher salt concentrations.
What is the dose for a swim spa or hydrojet pool?
Use 20ml per 2,000L for initial treatment. Maintenance: 10ml per 2,000L every 1–2 weeks.
Does Sanitify meet EU wellness facility water quality standards?
Sanitify is designed to work within EU wellness and spa water quality regulatory frameworks. Maintain alongside a documented water management plan and regular testing.
Can guests with skin conditions use Sanitify-treated spa water?
Yes — Sanitify-treated water is free from chlorine irritants. Particularly beneficial for guests with eczema, psoriasis, or contact dermatitis.
How long does Sanitify take to clear cloudy spa water?
Mildly cloudy spa water (from body oils and cosmetics) typically clears within 24–48 hours of Sanitify dosing. Run filtration at maximum flow during this period.
Where can I order Sanitify for our spa facility?
Available in the online shop. Commercial accounts with regular delivery schedules are available for hotel groups and spa chains — contact our commercial team for volume pricing.
