    How to prevent biofilm in Spa? O-Care?

    Thank you JoyfulNoise! I guess then Ahh-soome can be used the same way as O-Care claims but perhaps both better and cheaper.

    How to prevent biofilm in Spa? O-Care?

    Thanks a lot Kim! I did not clean the spa before using it the first time (didn't know I was supposed to). When I changed water the first time (after 5 months) I used pipe cleaner and it was a lot of biofilm coming out, more than the other 6 times I have changed water. I read the link about...

    Questions regarding Spa chemistry that is not found in my manuals

    I live in Sweden/Europe - so excuse me if my English might be rusty. I have found this forum giving me better information than most professional dealers in spa-products. My experience is that information is limited and dealers sometimes just guess when they advise on different topics. I have...
