yeah you are doing something wrong. Sort out your process and use it properly. Are you using really alkaline water?
To be clear we are talking about shop bought water here. Specifically Tesco Ashbeck water. It used to stay crystal clear for ages, now it doesn't.
This is my starsan after 2 months. Made using RO water from my unit.
This is what Tesco Ashbeck goes like after two days, and specifically Tesco, I've not tried Asda Ashbeck. Basically like bath water. The ph may be 2.2 but there's no way I'd use it as no rinse for my kegs. Yes it will kill the bugs, but your effectively adding soap in there.
