Anyone experience any issues running new cold water right into the sump after a wc? I am trying to figure out if the bacteria will have temperate shock
mixture of time and space. Plus right now I am changing probably between 300-400 gallons and i am not fulling running. Don't have the time to stagger and only have a 50 gallon water heaterWhy not stagger your water changes? Or maybe get a big drum and fill/heat ahead of time?
