These spas cannot transfer diseases to humans,you are at no more risk than a visit to the swimming baths. We use state of the art filtration system in each of the units so the water is constantly circulated through the filters at over 1000 litres per hour and filltered down to 5 micron reducing bacteria by 99.99%. It is sterilized thoroughly, 22 times per hour using uv sterilization to ensure the health and safety of our clients,staff and of course our fish! A 25% water change is also done every other day.
It is essential that clients fill in a disclaimer form and by no means can they use it if they have any open wounds, verrucas etc. If they have a tiny cut - which is scabbed over, not fresh (perhaps where their shoe has rubbed) we give them a waterproof plaster. Sarah22... the reason your friend was bleeding was because the fish automatically go for the dead skin. This is why if its a small enough cut a waterproof plaster can be used to cover it up.
Although the fish pedicures are good for eczema and psoriasis, it is important that there are no open wounds where the client has been scratching.
Because the water is constantly filtered, by the time the next client has come in, signed the disclaimer and cleansed their feet with hot cloths, the water is clean ready for them to use.
I understand where they bad news spreads from, because before my mum opened her fish spa we trialed many salons, and we too experienced bad service.
Please dont let this put you off because there are good salons out there!
