Questions

Common questions about your order.

How do I dose WhirlBiotic?

Start phase: 30 ml daily for three consecutive days. After that, dose once per week — the weekly amount depends on your water volume (30 ml up to 1 m³, 50 ml up to 2 m³, 100 ml up to 4 m³, 150 ml up to 6 m³). The full dosing table is on the How it works page.

How fast is shipping?

Orders are processed within 24 hours on business days. Within Germany, packages typically arrive in 2–3 business days; to other EU countries in 3–5 business days.

What is your refund policy?

Consumers have the statutory 14-day right of withdrawal. Original-sealed bottles may be withdrawn during that period and returned with our free DHL label. Opened bottles are excluded from withdrawal for hygiene reasons; statutory warranty rights for defects remain unaffected.
