Re: Star San/Hard water
If you use acids to adjust your alkalinity, then use that for your StarSan water. I use sulphuric or phosphoric.cellone wrote:What I would like is an answer to achieving a low ph in hard water. Could vinegar be the solution?

Re: Star San/Hard water
It's not the alkalinity that cause it to go cloudy, it is the chelating agents in the star san complexing with the calcium in the water, while adding acid to reduce the alkalinity will help with the long term stability of the pH, it does not go a long way to eliminating the cloudiness (it does reduce it though) . . . . However, throughout my brewing career I have always equated cloudy sanitiser with contaminated . . . and therefore, can't bring myself to use it if it is cloudy. Also I'm 100% behind Martin, the sliminess is yet another no no, given the length of time I leave 'syphon' tube and bottles in contact with starsan anything that promotes or assists with teh formation of biofilms is a big no no

Re: Star San/Hard water
I see that my post above reads like I use acids for my StarSan. I don't, I use them for brewing water adjustment. I never bother with tap water for my StarSan solutions. I go straight for Ashbeck from Tesco. It's so cheap, why bother faffing about?

I do this but it still goes cloudy and the ph. is higher than 3.5.Dave S wrote:I see that my post above reads like I use acids for my StarSan. I don't, I use them for brewing water adjustment.

Re: Star San/Hard water
Thanks for the info Aleman. I oxi clean my brewing and bottling equipment prior to using it. Would this remove the bio film provide a clean surface ready for sanitation? I rinse thoroughly after use and then clean and sanitise a few hours before use.Aleman wrote:It's not the alkalinity that cause it to go cloudy, it is the chelating agents in the star san complexing with the calcium in the water, while adding acid to reduce the alkalinity will help with the long term stability of the pH, it does not go a long way to eliminating the cloudiness (it does reduce it though) . . . .

Re: Star San/Hard water
If you are in a hard water area and you 'soak' in oxiclean for much more than 15-20 minutes you are in danger of creating a calcium 'scale' film that is a right PITA to shift, and even worse, rough allowing all sorts of nasties to get a purchase. A short soak in oxi clean will remove the biofilm though
