looking to add a preservative to my DIY foods so it wont spoil. going to use it for my auto feeder so so my foods will my liquid. could anyone help with this.
I wouldn't add anything to a reef tank that could prevent bacteria in seafood for four days at room temperature, aside from soaking it at low pH (as in vinegar) or high pH (limewater/kalkwasser) or high salt (like a brine solution).
