sharpstick Posted May 15, 2022 Report Share Posted May 15, 2022 We are currently using bromine in our Saluspa vinyl spa. It seems to work well, but we've been getting slippery slime on the floor. On a hunch, I recently put in two cups of colloidal silver and the slime has disappeared. (We have a CS generator, so it costs practically nothing.) How do other silver products work?

waterbear Posted May 16, 2022 Report Share Posted May 16, 2022 Silver will kill biofilms and algae but, like copper and zinc, is not a FAST ACTING sanitizer. Silver based algaecides have been on the market for many years. and the Nature 2 and Spa Frog products are silver based. However, none of these are a replacement for a fast acting residual sanitizer such as chlorine or bromine because the kill times for pathogens are too slow. 1 Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted May 16, 2022 Report Share Posted May 16, 2022 Yep. Still need a sanitizer. Not sure what levels of silver you are creating by your method, and also not sure of what levels are safe to be in, but I'd suggest you do a little research if you and @waterbear don't know either. 1 Quote Link to comment Share on other sites More sharing options...
